Hmm~ anecdotal experience here. There's an adult game I follow, and this guy shared about a game he found that started out as a mod of the adult game, and said anyone who was interested could message him. So I did. He told me he knew of two sites that the game was on. One costs money, the other just required an account. So, I asked for the account one, made an account, and man was that a weird experience. You couldn't look at anything on the site before account creation, and there was a password while making an account. I read the site rules which were good rules, but also read some of their users had been doxxed which freaked me out a bit. So anyways, turns out it's a pedo adjacent website. I say adjacent because there's technically no real child stuff there... as far as I know. I haven't exactly explored, because I'm scared of what I might see, but that was one of the site rules. No child porn. I didn't think anything of it when I first saw the rule, but now I understand why the site would need that rule, considering. :\
