Someone I know (in the UK) was arrested and spent a day in a cell when some criminal postings to Twitter were traced to his Tor exit node. When the police interviewed him and admitted they _knew_ what a Tor exit node was, and that he was unlikely to be responsible for the traffic. But they did want him to know that running a Tor exit node makes their life harder, and would land him in this sort of trouble. (I can't remember the exact words he reported, but it was outright intimidation).
