Hi, let me try to clarify my point so we don't get into a pointless argument.
I haven't played your game and I don't know the criteria the staff used to ban it (and they'll probably never tell us the reason). So I can't say whether the staff made a mistake in your case or your friend's.
All I'm saying is that Itch doesn't ban games JUST for being NSFW. Proof of that is if you go to the main games page, and you'll see it's full of games with NSFW content, many of which were there before the issue. So no, Itch didn't ban NSFW games, but they did ban those they thought violated the Terms of Service.
Could they have made a mistake? I'm sure that's the case, and that many games that shouldn't have been banned were. I'm also certain there are indexed and functioning games that violate the Terms of Service and haven't been banned, but those errors are NOT the norm. They are isolated cases, and that's the difference I'm emphasizing.
I sincerely hope the staff reinstates your game or at least explains the reason. But again, I'm not saying anything against your game. All I'm saying is that your case is an exception, and the proof is simply to look at the "popular" page.
