Even thos it will be hard,it will not be impossible,since somewhere in the connection your ip was logged. But unless a court order has been issued,i don't think they will bother to look thru out all those records and sessions.

As far as doing anything illegal from your house,well i wouldn't recommend it. Try a library or a internet cafe. Now,scams are scams no matter what,but ****** cards smells like Feds on the hunt.
If you're using thor,also visit guardster .com and use the free http:// feature for a little bit more protection.
Now..i wonder... theres a diff. encription used in europe,and i hear it's illegal to use it in the Us,anybody has any knowledge about that?

My respects to you guys.......
