That sucks... I literally only used ITCH.io for this... Now I tried searching again under the 'erotic' category and they literally deleted all the games...
I was actually planning to buy a few, but will those also disappear from the library or not?

All of the games under adult, erotic and some other tags are shadow banned meaning you can't look for them on the main page. Also some games have been completely deleted that included incest. My advice would be to just wait until we get more info on the situation before purchasing any game from itch.io.
