It's not called SOPA, but Notice and Staydown. It takes some of the content from SOPA though.
Basically, you can upload them and all, but if someone sends in a notice/complaint about it, a site is REQUIRED to take it off and forbid it from uploading again. Because it's to be automated instead of manual, content checks don't happen, so a lot of people say even "legalised" content can be taken down or a bogus notice can close a work. Once a work is closed, the site has to block you from posting it again unless you change the content significantly.

Stop SOPA-like policies in the Trans-Pacific Partnership, Notice and Staydown efforts, and other policies
SOPA may have been stopped, but large companies with many copyrights are trying to re-institute portions of it under other names and policies. This attempt to limit protected speech in the name of copyright is unacceptable, and must be resisted.
Secret negotiations to include SOPA provisions in the Trans-Pacific Partnership, lead by a former SOPA lobbyist, draconic Notice and Staydown measures that would hold small websites accountable to electronically police media with software they can't afford, and private agreements that could be used to bully small companies into excluding protected content are all being proposed now by Big Media.
We encourage the administration to oppose any measures that would deny alleged copyright infringers due process and protect original content!
USA politics effects pretty much the rest of us through the united nations lobbyists. Denk maar niet dat wij daar geen last van zullen hebben. De NSA bespioneert ons al jaren.So happy that they don't do this stuff in Europe.
