Sadly the monster genre has pretty much the same problem (along with beast, incest, noncon, all the shit that all the Patreon stuff had to clean out). 95% of it comes down to payment processors - namely MasterCard. They have a policy that doesn't allow anything that isn't pretty vanilla - the content is totally legal and no issue but Mastercard won't let you use them as a payment processor, and they are the biggest payment processor on the internet.
The only place left is Subscribestar, but it's not like they are allowed to do it, they are breaking MasterCards ToS, they just haven't been called out on it yet (the same thing that happened at Pixiv). There is actually an FTC investigation being done into MasterCard stopping sex workers and such from making money on legal content with their ToS. Would be nice if they were forced to back off, would really make things easier for everyone. Until then everyone has to try and navigate their restrictions (Hi there "Landlady" games). Its really really fucking annoying...
