Waterfall is very much a tiny baby atm, but it’s (1) The Tumblr Format, and (2) stated without any hemming or hawing that “Art of minors in sexual situations is not allowed and will result in a ban.” (Fuck you pillowfort!)
It also already has features like this
that tumblr SHOULD HAVE HAD FOR YEARS
So imo it’s definitely at least worth keeping an eye on.
To be clear, Pillowfort stated some mealy-mouthed “we’re not going to Police art of teenage minors bc it’s 2 hard uwu” bullshit, and after getting pushback on that, made a follow-up post waffling about how Pedophilia Is Bad But We Don’t Want To Be Checking Anime Wiki Pages For Characters’ Canonical Ages!!!!
Instead of just stating “we do not allow CP / sexual depictions of minors, Period” which is the ONLY acceptable position on the matter
