To be clear, the specific issue is hypno. Hypno is specifically against Patreon's rules, either written or unwritten, and you WILL get nuked eventually if you try to create an account there and do hypno stuff. Are there artists there doing hypno stuff (and all kinds of other stuff that's against the rules)? Sure. They haven't been reported yet. As soon as someone decides to report, you're done. Have seen it happen several times.
That said, several people have asked over the past few months, so I may eventually open up a SubscribeStar if people just want a way to automatically toss $5 a month at me. There wouldn't be anything extra for it, but if enough people want to donate that way I may look into it eventually.
