Ninja'd to it, but I'll elaborate a bit:
HalcyonSpirit, you are thinking of PIPA, a somewhat watered-down version of SOPA. They are both being pushed for by the entertainment industry, but I believe SOPA gives companies the right to sue OCR from even existing. Not just DNS lookup refusal, but if it's not hosted privately, they can force the serverhost or ISP to block it, possibly by refusing IP traffic as well (If this is possible, then http://69.16.252.101/forums/ will not connect you to the forum index of OCR)
