SOPA, the House version of the US Senate's PROTECT-IP Bill, might be the worst-ever copyright proposal in US legislative history. The Electronic Frontier Foundation has begun a series of articles examining the bill in depth, explaining just how insane it is. Here's part one:

If an IP rightsholder (vaguely defined – could be Justin Bieber worried about his publicity rights) thinks you meet the criteria and that it is in some way harmed, it can send a notice claiming as much to the payment processors (Visa, Mastercard, Paypal etc.) and ad services you rely on.

Once they get it, they have 5 days to choke off your financial support. Of course, the payment processors and ad networks won't be able to fine-tune their response so that only the allegedly infringing portion of your site is affected, which means your whole site will be under assault. And, it makes no difference that no judge has found you guilty of anything or that the DMCA safe harbors would shelter your conduct if the matter ever went to court. Indeed, services that have been specifically found legal, like Rapidshare, could be economically strangled via SOPA. You can file a counter-notice, but you've only got 5 days to do it (good luck getting solid legal advice in time) and the payment processors and ad networks have no obligation to respect it in any event. That's because there are vigilante provisions that grant them immunity for choking off a site if they have a "reasonable belief" that some portion of the site enables infringement.
