I mean, if it's real bad shit like violence, that's where FBI comes in, right?

Not sure if the ACLU would be able to do anything about hate speech.

But bad actors would have to run a shell game of go between instances to recruit. And they've been doing that shit for decades anyways. Hell, it's the same thing as under 18 punk shows back in the day when nazis hung in the parking lot trying to give booze/drugs to kids.

Like, imagine if someone said we can't have phones because assholes can also buy a phone...
