To add to Barhandar’s post, there’s also the way their ads were exclusively for furbooru for a month or two (at least; that’s around when I stopped paying attention to the site). They were pushing it super hard, and that combined with the contents of the admin discord leaks shortly before gave the sense that they were wanting to eventually merge the two.
Then Derpibooru admins got jealous of it and rushed its implementation on Derpibooru without talking to anyone
they put a bunch of tags that are not necessary to the image itself or “op is starting shit” just to bait and cause derail in comments.
It’s pretty simple logic, if completely retarded.

I even see plenty of nsfw aryanne pics in Derpi with a generous amount of likes and part of dislikes, kinda like with the Trixie is trans images.
