@Lymus first of all, thank you for the reply.
"they have no link to some other page or anything like that."
because the previous chapter that you removed an hour ago, which had credit page at the end like that, I commented on that one mentioning rule 3.2.6.
Conveniently, after that chapter was removed, another new account show up posting "who-knows-which-chapter-that-even-is", with 400+ chapter gap. Coincidence or not, I shall let you decide, but fyi this is a known pattern.
I tried looking up that same identical chapter everywhere else, and the chapter number was ranged from 516 to 550, both raw and translation.
So if this doesn't violate rule 2.1 or 3.2.6, then perhap 2.3.5: "
Joke or troll releases are not allowed, except on April 1st." ? The missing gap warning does mention this, and the only case where it's not correct is when previous group pull off their release, which cause the gap. "
partially uploading releases" is definitely 3.2.6, but the reason is still too vague.
Again, this is just my opinion, but it's really annoying when new accounts from nowhere start uploading licensed webtoon. (which show up on my feed, geez)
Thank you again for watching over filed reports!
