Re: Then what is the point of Tor?
When someone comes to you and says "hey I've got this great new community where everything you do is completely anonymous and you can do anything you want regardless of how others view such behaviour" there are three possibilities:
1. It's a complete scam, and the owners are collecting info on people for blackmail purposes,
2. It's a complete scam, and the owners are a law-enforcement agency looking to [en]trap criminals, or
3. It's an honest endeavour, which either has or will soon attract the attention of the people in (1) and/or (2), who will find a way to exploit it to their ends.
It's not even a zero-sum game. Say you play the game and use the community for completely innocuous purposes. At some point, either the 1s will mock-up something embarrassing, or the 2s will make it a crime to even be associated with the community.
