If you're a shithead in a club, you get kicked out. If you're a shithead with your family, you get kicked out. If you're a shithead on the internet, you also get kicked out.
Google (and facebook, twitter, paypal, etc) does that with regularity today, every once in awhile someone with reach in the tech community has it happen to them, some programmer or researcher, etc and it makes the news here but political commentators are banned every day off google sites because some one with enough influence on twitter targeted them for being a "shithead" in their view.
