I ticked adult content because I was worried that a few games I like wouldn't show up in search, such as Bad Parenting and Doki Doki Literature Club. Removed the tick and didn't see the game. Happy it was properly tagged at least, it just seemed to come out of nowhere. Definitely not ticking that box again haha!
Anyway I just saw it on the page for popular games, it may have been reported already but I'm less concerned now that you've said it's not necessarily an issue.
