Yes the thing is I have friends who make NSFW games who didn't know about this because they're just not tuned in on SNS or to analyticsand the SFW developers who are aware tend to be involved in NSFW spaces.. IE devs like the Heavensent dev.
And yes, Itchio is so bad... at making minority content viewable. It's one thing I was getting at via the nature of tags. The ability to not exclude anything makes this problem worse. The fetish community and the LGBT community on Itch have a lot of tag overlap which makes things more difficult- especially since a lot of the time it is beneficial for people in the LGBT community to use fetish tags (or to embrace these tags wholeheartedly for a variety of reasons).
A lot of queer people join game jams which helps a lot bit but maybe one day Itchio will make curated collections or the collections of users a core part of the site you can actually look at.. I sometimes find games via just looking at the analytics of collections my games are in haha.
