Finally got the contact email from neocities, it is entirely false that they're banning NSFW art, but they are making new terms, but are apparently comitted to not being like all the other websites. One of these terms I have been told is that they will make it mandotiry for NSFW art sites to have a consent to seeing page for NSFW art material, which means if you already do this, then congrats you're safe for now.
