The last place I worked paid hard-earned money during a recession to migrate their properties off of CloudFlare because they were providing CDN services to the Proud Boys and the CEO had made some equivocal statement that they didn't think it was their responsibility to police content. It's an interesting topic and possibly a genuine slippery slope about what sort of responsibility service providers have over their customers use of their platform. It's one thing for dangerous content to be hosted, moderated and monetized on a platform like facebook. But what about just caching it blindly?
