And yet, no one wants to police that. So... Cloudflare did it themselves.
I mean, look, I get the principled point you're making, but it's on really shaky ground. Either the conduct on that site was garbage that should be removed or it wasn't. And if it was... well, good riddance.
After the third (third!) mass murder advertised on the site, I think the time for principled and careful consideration has passed. Shut the garbage down, then we'll figure out if there's a better way to police this stuff going forward.
