The powers that be have decided that entire Pokemon and Digimon species are now to be considered cub, and therefore banned from the site.
Do they say exactly which species? Of course not! That would be too clear and obvious a rule!

Is Riolu banned? Probably!
Squirtle? I guess so.
Impmon? Sure.
Pikachu? Maybe!
There are ~5,000 Adult rated pieces of Riolu art on the site, so... good luck to everyone deleting all of that.

Honestly, from experience, it's going to come down to "Does the mod who sees the report against your Pikachu like / know you?". It's an arbitrary line drawn specifically to be vague, so that any nebulous undesirables can be removed.

Obviously the FA top brass can run the site however they like, make whatever decisions they want to make, and incompetently implement whatever policies they see fit. It's their boat, we're all just sailing in it. I'd have been sad about this at one point, but the road FA's been walking down has been very obvious for a very long time.

Once I'm inevitably banned, I'll be on InkBunny, Twitter, E621, etc.
