I got an email from an ISP some 2 - 3yrs back. It was from CBS network and they had seen my ip address was being used to torrent The Good Wife. So they wrote to the ISP and told them they must take action to stop the individual user of that ip address from pirating their shit or they will take action against both the ISP and the user. I stopped torrenting all CBS shows after that, i got paranoid and figured my public ip was probably on some watchlist
