 SOPA (PDF), which is modeled partly after the Senate's PROTECT IP act, will allow copyright holders to obtain court orders to block sites that allegedly infringe on their property. Targeted sites would include sites operated for the sole purpose of infringement (or that "have only limited purpose or use other than" infringement), as well as any site that "engages in, enables, or facilitates" infringement.

The heavy-handedness--and broadness--of the bill is troubling to many people. The Electronic Frontier Foundation (EFF), calls SOPA "disastrous" and "the worst piece of IP legislation [they've] seen in the last decade." 

According to the EFF, SOPA would essentially allow copyright holders to force service providers to "disappear" certain websites, which endangers both Internet security and sends a "troubling message to the world: it's okay to interfere with the Internet, even effectively blacklisting entire domains, as long as you do it in the name of IP enforcement."
