Thanks for the information! That helped clear up my confusion without having to delve into the anxiety of searching specific terms. I knew of all the hate crimes and other atrocious stuff, but for some reason managed to never hear about the CP associations with 8chan.

Just goes to show how either clueless or full of shit the CEO is, I guess, since such a huge point was made in the blog post to insist they definitely totally deny service to anything related to CP yet there he is expressing regret for denying service to 8chan. What a shady look for Cloudflare...
