If you look on Disboard and such, it is trivial to find sexually explicit Discords aimed at minors, and even more troubling, ones that are sexually explicit, allow minors, and adults ("age range: 14-28").
There's going to be a newsworthy incident, soon, I'm sure of it.

What's interesting to me is that in twenty years we've gone from "use the internet with parental supervision, don't use your real name, and don't talk to strangers online" to making platforms pick up the slack of parents and law enforcement to prevent predators talking to kids.
Now I'm not saying that platforms like Discord shouldn't be doing a better job policing things, but it's also shocking to me how much the expectations of these platforms has changed in twenty years. AIM was way worse than Discord is today. Predators used to hang out on Runescape and Neopets. I feel like we're taking too much onus off of parents to monitor their kids online access.
Now we look back at the world of AIM and ICQ and IRC as being just as bad.
