Patreon does open the door to uncensored content. For example F.S. a notable artist who is behind some of the Queens Blade art, they post uncensored work on there and censor it on Pixiv.
Wish a few more would do the same. Matsumoto Drill being one and the author of Kunoichi being another. Think I mentioned it to them too. but Drill was putting up actual uncensored stuff for awhile and now he's had to censor it because they caught on and took some down.
