Websites that host user content

Opponents have warned that SOPA would have a negative impact on online communities. Journalist Rebecca MacKinnon argued in an op-ed that making companies liable for users' actions could have a chilling effect on user-generated sites such as YouTube. "The intention is not the same as China’s Great Firewall, a nationwide system of Web censorship, but the practical effect could be similar," she says. The Electronic Freedom Foundation (EFF) warned that websites Etsy, Flickr and Vimeo all seemed likely to shut down if the bill becomes law. Policy analysts for New America Foundation say this legislation would enable law enforcement to take down an entire domain due to something posted on a single blog, arguing, "an entire largely innocent online community could be punished for the actions of a tiny minority."

Additional concerns include the impact on common Internet functions such as linking or access data from the cloud. EFF claimed the bill would ban linking to sites deemed offending, even in search results and on services such as Twitter. Christian Dawson, Chief Operating Officer (COO) of Virginia-based hosting company ServInt, predicted that the legislation would lead to many cloud computing and Web hosting services moving out of the US to avoid lawsuits. The Electronic Frontier Foundation have stated that the requirement that any site must self-police user generated content would impose significant liability costs and explains "why venture capitalists have said en masse they won’t invest in online startups if PIPA and SOPA pass."

The SOPA isn't just some normal anti-piracy act to america. What I've heard is that it will threaten any site that features content anywhere else other than on the original sites. Sites such as Danbooru and YouTube could be shut down if even one unauthorized content is found there. Not just those, even Google and Yahoo are at risk.

The important part:

They can, because if it was based in the US, it goes under US rules. It's like how some videos in YouTube aren't available in other countries.

Yes, it says that only English Wiki is blacked out, so I can read the Chinese Wiki fine. :3
