WAIT I FIGURED IT OUT... they are taking down explicit incest games and in the meantime shadow banned other games
Viewing post in adult and erotic tags games gone?
It's not completely unrelated. I can bet you that it's due to the pressure that's being put on by payment processors like Visa and Mastercard, they've been going after any and all forms of "controversial" nsfw material because they're not capable of differentiating between drawings and real life problems. Incest falls into that category so therefore it's related to this problem.
