For best security you should run a TOR node.
You have to put up with annoying emails from various copyright holders as they all seem to think the TOR traffic is yours. Once informed that the ip is a TOR node they cease their pestering ways.
Or, perhaps, they don't - and you end up arrested. There is no way to separate your activities from activities of Tor users that you facilitate. So if someone connects to port 22 of some server at Pentagon, the FBI has legal right to come after you.
Running a Tor exit node is just as smart as standing in the street and doing everything that some stranger tells you to do over a cell phone. Like "Find a nearest cracker and hit him in the mouth."
