Uploaders might really have to fear something, but uploaders should protect themselves either way. And who cares anyway. The only one who's screwed is Kimble, and he's used to being screwed. xP

Anyway, you should consider one thing: If something like this is possible without SOPA or similar crap, why is it needed then? The take down of megaupload had the worst possible timing, it is the best reason to not create bullshit like SOPA. Sadly all I hear from Americans is "oh noez it's gonna get far worse with SOPA". Oh c'mon...
