We have been known to delete random crap that’s pretty much a one-off pony vector and random text strapped on it. The problem with memes is they’re almost all crap, yet somehow popular. Other than chikun and flash sentry, these things are uploaded by dozens of different people. Most
seem to dislike them, but there’re enough that apparently like them for reasons we don’t comprehend. Given they don’t really break any grand rule on their own (not illegal, not offensive, and are, to some degree or another, pony related) I can’t really advocate an option for a full on ban.
This is a bit different from what we did with the cum on toy stuff, because that’s a binary “the toy has cum on it, or it doesn’t”. This topic includes an obnoxiously wide variety of different kinds of images and “jokes” of some quality or another that are too difficult to judge. I have
had a few chuckles from some of these, and I can easily imagine there are people that find as much enjoyment from these things as they do from “real art”.
