Charles tweeted this handy guide for website owners yesterday.
It’s worth another shot if someone from Fox (or one of Breitbart’s sites)
is reading this thread:

Anil Dash: If your website’s full of assholes, it’s your fault

This one stands out:

You should have community policies about what is and isn’t acceptable behavior. Your community policy should be short, written in plain language, easily accessible, and phrased in flexible terms so people aren’t trying to nitpick the details of the rules when they break them. And then back them up with significant consequences when people break them: Either temporary or permanent bans on participation.

It’s not enough just to flush the crap occasionally and pretend it wasn’t there.
