As far as I know, there's no longer a problem with accepting donations and payment on NSFW projects. However, that definitely gets them delisted from itch's search menu.
It'd be nice if I could get official confirmation from itch themselves given that the consequence of doing so, at least immediately after the censorship wave, was being permanently banned without appeal.
I won't disbelieve it, but I didn't hear of that happening to anyone (aside from that one game that made headlines). It was really bad, they de-indexed all NSFW for a time, but there was also misinfo going around. Would be nice to have more direct communication from itch, of course.
Yeah, I helped with one of the groups organizing against it. However itch's response was real...though it does seem like the best way to contact them is through social media at-mentions, which I'd really rather not do.
