I have encountered multiple confirmed underage players on MUDs.
In one incident about 4 years ago, the game had a Discord server with an active voice chat. A player told us openly they were 17 and applying for university the following year. A second player whom I believe was roughly my age (Millennial) then proceeded to repeatedly and frequently hit on the underage player. What frustrated me is that when I tried reporting the issue, I was told that the underage player had a reputation for acting horny and liking that kind of attention, so it was probably OK. I spoke to the underage player directly about the issue, who made clear to me that the older player hitting on them made them extremely uncomfortable, and that they wanted it to stop.
It does happen, and people should be extremely vigilant about it.
In all candour, I started playing MUDs when I was 11. Stuff did happen. I recall a 12 year old girl on the same MUD had that same kind of “reputation” with older male players in the community, and in hindsight, I genuinely can’t believe staff just let that happen. Dark side of the freeze-peach crowd, IME.
Personally, I am fully in favour of age verification laws, based on these experiences. And I’m in the UK where they’ve already been rolled out.
The issue generally isn’t TS. Like, whatever, teens masturbate. It’s that people tend to take these conversations OOC, where there is a power imbalance between younger/older players, which enables predators. Particularly on games which tend to be rife with mentally unstable individuals, and settings which tacitly promote all kinds of fetishes (and I’m not just talking about sex games), I don’t want these to be the formative sexual experiences of any child.
