I got a weird email from Patreon today:
This had me pretty worried at first, but looking closer at their policy on "Sexually Gratifying Works" I see this:
Works which are sexually gratifying or contain nudity and abide by all other guidelines are in many cases permitted on Patreon pages categorized as Adult/18+. The public-facing spaces (e.g. profile image, page banner, tier descriptions) of Adult/18+ Patreon pages must be free of sexually explicit material or nudity, real or animated, in any format: photo, video, written, or audio.
So I think the problem is the title "BDSM", which may be visible to the public? I'm not entirely sure, but just in case I'm going to remove all my other collections too (not the images, just the groupings). You can still search for stuff based on tags.
Hopefully there will be no trouble moving forward. I do also have a SubscribeStar account going, just in case...
