As a reminder to everyone out there, multiple ISPs launched a "six strikes" program yesterday in collaboration with content groups like the RIAA and MPAA. If caught by a copyright holder, the ISP will try to contact the account owner of the IP address in a similar way to how a credit card company contacts you if fraud is detected on your credit card. If caught more and more times, notifications such as popups, pages failing to load, slowing down your internet speed, "or other measures that the ISP may deem necessary to help resolve the matter."
If caught up to four times by a copyright holder, the ISP's will introduce "mitigation measures." These measures include things like slowing down your internet speed or page redirects to pages discussing copyright infringement (that last until you contact your ISP). If you get caught after those measures, they will continue to repeat the measures. While they say that account termination isn't a part of this plan, they're within their (legal) rights to terminate your account. If you want to protest the ISP thinking you're infringing on someone's copyright, you will have to pay a $35 "filing fee." There is a chance that fee will be waived, though.
If you want to read FAQ's on this plan, check it out on dlsreports.com (pdf). The plan may sound good on the surface, but (as usual) the Electronic Frontier Foundation has some problems with it. You can read their take on the plan here.
