Update: So it looks like after you've searched to check, you should avoid the site, because they might be able to further use it against you. For now, there is more information in 's journal here: [link]
Please go check out her journal, she already has a formal notice for take down linked there.
I just got informed of this, but the site dramakoreaterbaru.com has been posting art without artists permission. My own is also included in this. Though the admin has clearly put things like "By _____" for the artist, the very fact it's up there without being asked first is rather troublesome.
Like others, I have referred friends to use the search on the site, and see if their art has also been posted.
If you also have had this issue, the person's contact information is below, in case you would like to ask them to take your things down.
