According to the rules in the US and Canada, Comcast forwards copyright infringement notices to subscribers who have allegedly downloaded torrents. These DMCA notices list the title, IP-address, and other download details. They are also accompanied by a stark warning notifying the subscriber of a possible account termination
The subscriber, who posted his story on Reddit, was sent 44 letters for one and the same torrent. The Spongebob Season 8 torrent was downloaded by his brother and is apparently well tracked. Usually, alleged downloaders only receive one letter per offence, but one Comcast subscriber received a whole stack in the mail this week.
According to Reddit's user story:To prevent their IP-addresses from being tracked, thousands of people have signed up to a VPN service. Using a VPN allows users to use the Internet anonymously and prevent your ISP from monitoring your online activity on the web. The best VPN services don’t log any traffic nor session data of any kind.
