Policing content isn't the same thing as stopping active damage to the internet. Even in the US where free speech is king, you can't go around slashing tires or taking down stop signs and say it's protected by the 1st amendment or something.

Not sure how he pulled this one off, considering Amazon is now requiring a verified SSN or tax ID for requesters to purchase money to post HITs, but there you have it.
