Protip: the pirate bay sucks. You're much better off (not to mention a lot safer) getting into a private tracker, even if it is a little difficult. there should be a subreddit for them.
TPB is the piracy site EVERYONE knows about, so you bet your ass that's where companies will be trying to bust people for copyright infringement.... even though most ISPs give you a few chances before suing you, the last thing you want is for them to be keeping an eye on you.
