@hingehead,
There's a duplicate thread on this, so here's a duplicate post
If this story is accurate, then it worries me.
If the FBI (or any government agency) can arrest the owners of any site just for allowing its users to upload large files, then almost anyone on the Internet who owns a server and has users could be held accountable for something their users put onto their server. And from there it isn't a far stretch to imaging providers being held accountable for anything that flows through their routers.
Under this paradigm Copyright infringement could be used as a legal pry-bar to open virtually anything on the Internet.
If they need to protect Copyrights (and I'm not sure they do in some cases), then I think they should only be able to go after the people who upload Copyrighted material, not the people who's systems they use to do it.
How come they don't arrest Bill Gates for allowing his computer software to be used to do all the copying?
