Very interesting piece in Roll Call:

Here’s a plausible campaign scenario under SOPA. Imagine you are running for Congress in a competitive House district. You give a strong interview to a local morning news show and your campaign posts the clip on your website. When your opponent’s campaign sees the video, it decides to play hardball and sends a notice to your Internet service provider alerting them to what it deems “infringing content.” It doesn’t matter if the content is actually pirated. The ISP has five days to pull down your website and the offending clip or be sued. If you don’t take the video down, even if you believe that the content is protected under fair use, your website goes dark.

The ability of any entity to file an infringement notice is one of SOPA’s biggest problems. It creates an unprecedented “private right of action” that would allow a private party, without any involvement by a court, to effectively shut down a website. For a campaign, this would mean shouldering legal responsibility for all user-generated posts. As more issue-based and political campaigns utilize social media to spread their message and engage supporters, a site could be targeted not only for the campaign’s own posts but also for well-meaning comments from supporters.
