So Cloudflare went from hosting everything that's not illegal, to kicking people out who claim that Cloudflare supports their ideology, to kicking people out with less than a day's notice on a Sunday if a forum attracts user-generated content that Cloudflare doesn't like - and the rules for content that they don't tolerate may change on similarly short notice with no warning before they decide to terminate your account (most likely based on "has enough media outrage happened").
Also, they stated that they were "cooperating around monitoring potential hate sites on our network", which makes me wonder what kind of monitoring we're talking about here, and whether and where else they share traffic that they're proxying.
Regardless of what you think about 8chan (I'm not familiar with the site but there seems to be consensus that it's a cesspool), these points are interesting to note.
