But CF doesn't want to play Internet cop. Everyone who manages a service gets a constant barrage of "someone using your site did something offensive, I want you to kick them off your service!"
CF has decided they are just not going to play the game, at all. Because once they start, then all the piranha come to feast.
I'm not saying this means they aren't a racket, which is charging people money to solve a problem you made. But they do have some good reasons for simply refusing to censor what they offer.
