Reviews on the Yeouya cafe: what to watch out for

According to WikiDoc's research as of November 1, 2026, clinic recommendations in Yeouya comments should be read as promotion comments, not patient reviews.

1. Three accounts split the day into 8-hour shifts to push Byul Plastic Surgery. Each takes night, day or evening, and no two of them ever commented on the same post.
2. One comment was posted on 339 posts with a link to a clinic sign-up form. The link in "I went on a friend's recommendation too, sharing it with you" opened a form with Brillyn Clinic's price list and fields for your contact details.
3. They copy someone else's experience and swap only the clinic name. Another person's "the place I had surgery" comment came back 8 days later word for word, with only the clinic name changed.
4. More than 900 accounts push the same clinic over and over. The clinic with the most such accounts is DA Plastic Surgery.
5. Likes are manufactured too. The same 124 accounts liked all five reviews that had hundreds of likes.
6. The front page is an ad board for clinics and companies. In a cafe with 2.32 million members, 16 of the 20 pinned notices and must-reads at the top are clinic or company posts, and the menus hold 21 boards named after clinics and 116 brand trial boards.

Yeouya is a Naver cafe. A Naver cafe is a members-based online community inside Naver, a Korean web portal. Yeouya is a large women's community among them, and people talk a lot about plastic surgery and skin treatments there.

Yeouya is a cafe with 2.32 million members and more than 6.8 million posts (front page on November 1, 2026). That front page is an ad board for clinics and companies. Of the 20 pinned notices and must-reads at the top, only 4 are cafe rules; 16 are clinic or company posts. Event posts such as QD Clinic's "up to 49% off EVENT in November", Mind Plastic Surgery's "Onda + Ulthera 130 EVENT" and Honesty Plastic Surgery's "nose revision 3.5 million won" hang above the cafe rules. Posts by Vance Clinic, Highvom Plastic Surgery, Ryan Plastic Surgery, U&U Plastic Surgery, V.LIF Plastic Surgery Clinic, ARC Plastic Surgery and 1percent Plastic Surgery also take notice slots.

The menu [Yeouya plastic surgery info & columns] has 21 boards named after clinics, such as DA, NANA, TS and Made Young. The menu [Writing event reviews] has 116 trial boards for cosmetics, food and pharmaceutical brands, and there is also a "Clinic events" board and a "Partnerships and trial inquiries" sign-up form. The cafe appears to be built to make big money from clinic and company advertising. DA Plastic Surgery, which has its own board, is also first in the promotion account ranking below.

Most posts are questions. Posts like "Does Ulthera hurt?" or "Is there a good place for a nose revision?" go up, and other members answer in the comments. For someone choosing a clinic, these comments are the reviews.

From late May to October 2026, WikiDoc looked at hundreds of thousands of comments on public Yeouya posts and grouped them by account. Tens of thousands of accounts wrote them. Only Yeouya and Naver know who runs these accounts. These data cannot show whether a clinic ordered it either.

Three accounts push Byul Plastic Surgery in 8-hour shifts

Three accounts name Byul Plastic Surgery in Seocho. "Mang**" comments only from midnight to before 8 a.m., "Uma**" only from 8 a.m. through the 4 p.m. hour, and "Haetsal**" only from the 4 p.m. hour to around midnight. They wrote 292, 690 and 420 comments.

• All three were active on 38 days. On September 16, "Mang**" commented from 1:22 a.m. to 7:39 a.m., "Uma**" from 8:09 a.m. to 12:18 p.m., and "Haetsal**" from 6:11 p.m. to 9:29 p.m.
• The three commented on more than 1,300 posts. Posts where two or more of them commented together: 0.
• They talk the same way. Whether the question is about a nose or breasts, they end with "consider Byul too" or "compare it with clinics like Byul." Even to someone asking whether light jogging is fine a month after a facelift, one replied "if you ask a well-known place like Byul."
• The three put Byul Plastic Surgery in more than 560 comments. Add one more daytime account ("ka**") and it is more than 600.

One person does not split a whole day like this. It looks like people working shifts, each pasting one clinic name.

"A friend recommended it" 339 times, and the link is a clinic sign-up form

From July 15 to October 29, "x**" posted the same comment on 339 posts: "Ulthera is so good.. I went on a friend's recommendation too, sleep Ulthera is a steal, such good value that I'm sharing it." Depending on the post topic it only swapped "Ulthera" for "Thermage," and it added a short link at the end.

• On October 14 it posted this comment on 51 different posts in 61 minutes, about one a minute. It went down the board list from the top.
• It never posted on a Sunday.
• Another account, "Haril**," posted the same sentence and the same link on 22 posts.

The link opens a Naver Form called "Summer Beauty Event." It shows the price list of Brillyn Clinic in Gangnam (Ulthera under sedation, 300 shots, 790,000 won; Thermage FLX under sedation, 600 shots, 1.89 million won, and more), followed by fields for your name, phone number and preferred date. Sign-ups opened on July 14, the day before "x**" started posting. It looks like a friend's recommendation, but it is an ad that sends people to a clinic's consultation form.

Copying someone's "I had surgery here" and swapping only the clinic name

On October 6, two accounts commented on a post titled "Where is hot for under-eye fat these days?" "Ppaeppae**" wrote "I recommend Oho Plastic Surgery where I had my surgery!! When I got under-eye fat repositioning I asked if I needed anything else…" and "Yueo**" wrote "Sketch is also a place many people go for under-eye fat…"

Eight days later, at 7:04 and 7:05 p.m. on October 14, "Alpong**" copied these two comments word for word onto two other under-eye questions. Only the clinic name changed. Both became "Hyundai Aesthetics." It took a first-hand surgery story from someone else's comment and swapped in a different clinic.

The same phrase, "Oho Plastic Surgery where I had my surgery," was also written by 12 accounts on 22 posts in October.

Case report: Someone else's "the clinic where I had surgery" comment, copied with only the clinic name changed

Take a short question post, "Is Ultherapy Prime bearable??". It got 17 comments. 14 of them named a clinic, and the clinic was different in almost every comment.

We followed each commenting account. 11 accounts were also recommending one clinic in more than 10 other posts. "Geurim**" named Blanc de Vie Clinic in 510 posts, "Bibim**" named Amiskin Clinic in 104 posts, and "Myulli**" named Ting Clinic in 81 posts. "Taeguk**", the first comment, named Reusel Cheongdam Clinic here, but named DA Plastic Surgery in 14 other posts. What the person asking got was not experiences but a lineup of 11 clinic promotion accounts.

Case report: Eleven accounts answered one question, and all were clinic promotion accounts

Posts like this are not rare. There were hundreds of posts where three or more accounts that had named a clinic in over 10 posts showed up.

One account, one clinic, hundreds of posts

They write like an ordinary member: "I had it done here and it was good." But their other comments show the same clinic every time, whatever the question.

• "Rullu**", "Orul**" and "Keol*" only look different on screen; they share one member key and are one account. It wrote 483 comments over 5 months, and 405 of them contain Face Dermatology in Mapo, across 396 posts.
• "Geurim**" put Blanc de Vie Clinic in Apgujeong in 527 of its 528 comments.
• One account left 146 comments on 143 different posts over five months. In 124 of those posts it named DA Plastic Surgery. All 146 comments were written on weekdays between 9 a.m. and 7 p.m. On one weekday in July it praised DA on three different posts within 16 minutes.
• Another account left 156 comments and named Sinsa Egg Clinic (written "Sinsa Egg" or "Egg Clinic") in 102 posts. 149 of the 156 were written on weekday daytime. Around noon on October 28 it posted about Sinsa Egg Clinic on 9 different posts in 28 minutes.
• 11 accounts brought up the same clinic in 100 or more different posts, and more than 200 accounts in 20 or more.

Case report: 8 posts in 16 minutes, one account pushing only one clinic

8 posts in 16 minutes, the same sentence

On the morning of October 29, "Jjeureu**" left comments on 8 different question posts in 16 minutes. All 8 are about Ulthera at MeSOnBom Clinic in Hongdae. The sentence "I looked around a few places, had it done at MeSOnBom in Hongdae, and it worked well" is almost the same each time. The last four comments show a different nickname, "Geu*," but they share the same member key and are one account. Over 5 months this account wrote 128 comments, and 120 of them are about MeSOnBom.

Case report: 8 posts in 16 minutes, one account pushing only one clinic

Hundreds of accounts left clinic-name comments on 5 or more different posts within 30 minutes. Dozens did so on 10 or more. Real patients rarely move like this. It looks like someone going down the list of question posts and pasting a set clinic name.

Pasting the script as is

"Wim*" and "Anu**" are different accounts. Yet the two posted the same two treatment-praise sentences, identical down to the letter, 28 times. One starts with "Thermage is good!". "Anu**" pasted them 15 times in a little over 2 hours from 11:30 at night. Both sentences name a clinic in Sinnonhyeon with only the initial consonants of its name. In other comments the two accounts write the name out in full: "Delight in Sinnonhyeon." It is Delight Dermatology in front of Sinnonhyeon Station.

Case report: Two different accounts pasted the same praise 28 times

Some comments went up with the script's blank still unfilled. "ka**" wrote: "Among clinics in Gangnam, I recommend "○○ Clinic" as a place where the doctor consults you in person and designs a natural result. I hope you get a satisfying result!" The "○○" was left where the clinic name should be. Of this account's 81 comments, 59 mention Byul Plastic Surgery, and it says again and again that it had surgery there.

Many comments drop a clinic name into one fixed sentence. The pattern "I had Ulthera at ○○ and it worked so well that I plan to keep it up once a year" appears in 319 clinic recommendations. 32 accounts wrote them, naming 23 clinics. MeSOnBom has the most with 94, followed by Hill House Dermatology, Onlybit, DOD, Reusel Cheongdam Clinic and Arna. 22 of the 32 accounts each pushed one clinic in more than 10 posts.

Case report: "I plan to keep it up once a year": the same sentence, only the clinic name changes

Some copied another person's body story word for word. "My skin is really thin, so thin that coughing hard gives me pinpoint bleeding, but I got a thread lift and I'm happy with how long it lasts and the effect!!" was written by "Rinyu**" on September 17 and by "ne**" on September 28. Six accounts pushing VS Line in Gangnam wrote almost the same sentence 13 times: "they design it to prevent hollow cheeks, and the tightening effect too … I got a pain shot in the buttock."

There were more than 100 groups of identical comments over 40 characters written by different accounts. That means one person runs several accounts, or several people paste from the same script.

One account pushing several clinics

In 40 minutes, "Ippu**" commented on post after post, taking turns recommending Cheongdam RETOO Clinic and Flores Dermatology in Isu. For Flores Dermatology it even named the doctor. 206 of this account's 278 comments are about these two clinics. "Bora**" in the first screen is this same account under a different on-screen nickname.

The place where this account says it had treatment keeps changing too. On September 10 it wrote "I got Onda at Renine in Myeongdong and booked a second session." On September 14 at 2:43 p.m. it wrote "I had my jawline done at Cheongdam RETOO," and one minute later, at 2:44 p.m., "I got 300 shots of Ultherapy Prime at Flores Dermatology."

Case report: An account whose clinic changed within a minute, taking turns pushing Cheongdam RETOO and Flores

There is also a pattern that pairs two clinics. "For [body part], I've heard a lot that [Clinic A] and [Clinic B] are good too; they're so famous and well reviewed that they stuck in my mind" was written by 6 accounts with only the pair changed: DA and NANA, Louvre and Top Class, Private and Louvre, PR and Yellow.

A recommended clinic is not necessarily the owner of the account. There are a few possibilities. First, it could be a marketing agency handling several clinics at once. Second, it could be one clinic's account that names other clinics too, because naming only one place looks like promotion. A lower-ranked clinic slips its name in next to clinics that advertise heavily or rank high in search. "Taeguk**" in the first screen, who named Reusel Cheongdam Clinic in this post and DA Plastic Surgery in other posts, is the same kind of case.

Clinics with the most promotion accounts

Clinics often have several such accounts. 38 clinics had two or more accounts that pushed them in more than 20 posts. Counting each account under the clinic it named most, the top looks like this.

DA Plastic Surgery had 99 accounts that pushed its name in more than 10 posts, 2.5 times the clinic in second place. Adding up, per account, the posts in which these 99 accounts named DA Plastic Surgery gives more than 1,600.

"I sent you a message"

When a commenter asks which clinic it was, the post author replies "I sent you a message." A message here is a private message inside the cafe. The clinic name and price disappear from the public post and move into private messages. Nobody can check who sent them or what they get from the clinic. In a public comment, another member could reply "That place was not good," but no one can dispute a private message.

Among the comments WikiDoc looked at, nearly 20,000 contained the word "message," on thousands of posts. Replies from post authors saying they had sent a message alone came to more than 10,000.

Like flooding

Likes on Yeouya posts are normally few. Of the tens of thousands of posts whose like counts WikiDoc checked, more than half had zero, and 99% had 25 or fewer. Yet some posts have hundreds of likes. They are surgery show-off reviews like "an amazing result" or "everyone who sees it says it's pretty."

We picked 5 reviews with 263 to 350 likes, pulled the list of accounts that pressed like on each, and compared them. They are 3 breast surgery reviews for Kai Plastic Surgery, 1 under-eye fat repositioning review for Inique Plastic Surgery and 1 nose surgery review for Highend Plastic Surgery.

• A little over 400 accounts in total liked the 5 posts. 124 of them liked all 5.
• 91 to 99% of each post's likes came from accounts that also liked 3 or more of the other posts.
• For comparison, we picked 3 ordinary popular posts with 20 to 29 likes at random. Not one account from this group was there.
• On the Inique Plastic Surgery review, which had the most likes, 349 of 350 likes came in within 3 hours of the first like. Over the next day it gained 1 more.

Of the 14 praise comments on that post on its first day, 12 were written by accounts from the same group that liked these 5 posts. They are short lines like "huge before-and-after difference" and "it turned out so natural."

Members notice too. A like-flooded Kai Plastic Surgery review got comments like "241 likes and 0 comments, lol", "looks like a broker" and "I should skip Kai."

Case report: 349 of 350 likes in 3 hours, and the same 124 accounts liked all five reviews

Posts with many likes go up the popular list and get read more. So the like count itself becomes an ad. The same group of accounts filling up likes on the same posts within hours is not natural popularity. WikiDoc sees it as promotion by the clinic side.

From late May to October 2026, WikiDoc looked at hundreds of thousands of comments on public Yeouya posts, written by tens of thousands of accounts. Tens of thousands of comments on other people's posts named a clinic, written by more than 10,000 accounts.

• The roughly 900 accounts that brought up the same clinic in more than 10 posts wrote more than 20,000 clinic-name comments. That is one in three (31%) of all comments that named a clinic.
• Clinics with two or more such accounts: 38
• Groups of identical comments over 40 characters written by different accounts: more than 100
• Comments containing the word "message": nearly 20,000 (on thousands of posts)
• Accounts that liked all 5 like-flooded reviews: 124 (0 on ordinary popular posts)

These numbers count only cases that left a trace. Rotating several accounts or mixing ordinary comments between recommendations slips past this method. Members-only posts are not included either. The real numbers are higher.

WikiDoc writes up each case as its own blog post. New cases go up on the blog first and are added here later.

• If recommendations in a similar tone line up on one post, each naming a different clinic, do not trust that post's comments at all.
• Do not click links in comments like "a friend recommended it, sharing it with you." They may be a clinic sign-up form.
• Sentences like "I looked around a few places and settled here," "not a factory clinic, the doctor does it in person" or "I plan to keep it up once a year" show up often in promotion comments.
• Do not contact anyone who will only tell you the clinic name by private message.
• Ignore like counts. If a post has hundreds of likes but only a few lines of praise in the comments, be more suspicious.
• An offer of a surgery discount in exchange for a review is a way to make promotional posts. Remember that such reviews are mixed in.
• Look up the same clinic separately on other sites.
