I checked the 'sensitive content' tab in MetaData for my new game Orange Roulette -- it's not Hentai or sexual in any way, it's just a scary Roulette game. Apparently doing this made all the adult content on Itch.io viewable from my account. I initially thought there had been a sudden takeover of porn games on the site! I turned the tab off today and all the porny stuff disappeared. The look of the 'Popular' and 'Top Seller' categories was VERY different for several days ha ha.

There really should be a warning popup or something, when people set this meta data, to inform them, that from now their account is set to have adult content enabled.
I suspect it was made to reduce complaints about people not finding their own game. (Not that there is a lack of people complaining about just that for other reasons ;-)
