Well, as far as I understand it, Itch took most of the NSFW game pages out of search. If you have a direct link or a bookmark, you can still get the full functional. Well, at least at the moment.
I think they took basically all NSFW games out of the search, at least all NSFW games with uncensored sexual content.
The thing is they started to ban some NSFW games for good.I never played one of the games that got banned.So i don't know if they ban only games with extrem NSFW content or if they ban all NSFW games, slowly but surely.
