Earlier this year we saw an increase in the number of reports we received about some people using our service in ways that we cannot tolerate. To be more clear, this was not about some people merely saying things that others disliked.
Over the past several months we tried multiple strategies in order to end the violations of our terms of service. However in the end, we determined that requiring authentication was a necessary step to continue operating meet.jit.si.
This sounds to me like a pattern of people using it for actual serious crimes (with the obvious guess being video sharing of sex crimes/trafficking/kids). I understand that that justification is used for a lot of extremely invasive privacy violations, and stuff like scanning every file in the name of that is too far, IMO, but if you're the only platform with resources to handle that traffic that allows anonymity, it's very likely to grow at a significantly larger rate than the rest of your traffic.
You can't (shouldn't) scan every file every individual sends to every other individual in order to prevent it, but once you have a platform that's capable of supporting community-type activity, it's a very real issue that you can face.
"You can host yourself with your own choices on vetting participation because here are the tools to do it" isn't really a bad line to draw. But you can't have your servers be a central point for that.
Most of the rest of Asimov is a lot more self contained than foundation. I like the rest of his stuff but Foundation is too abstract for me.
