It seems that everything small now is a child, that's the only explanation I can think of, like "resemblances of a child", and such. I really hope itch just get less and less used after everything else, they're pro censorship so that's absolutely bullshit for me.
I kinda agree with you but it all seems that they've used this as an excuse to already do this type of stuff, the creator of Itch never liked adult/hentai games, he had that opinion before and it was one of his reasons to found itch, to get rid of this type of content that every platform has, so, I really just can't think better otherwise.
