So I was thinking - after SOPA passes, what's to stop us (i.e. those opposed to it), from uploading copyrighted things to every site related to the people supporting it (RIAA, MPAA, movie sites, government sites) that have some comment feature or whatever.
And then requesting that those sites be taken down. Let loose 4chan and the absurdity of the whole thing will become clear.
Well, nothing would stop us from doing so, but whatever governing body has the authority to enforce SOPA will probably have exceptions for certain sites, especially to those who monetarily and non-monetarily supported SOPA itself.
SOPA is never going to be used on anything that the lemmings would notice (Facebook, for instance). The people who want SOPA in place can't risk losing the tolerance of the general public.
Except SOPA creates new private rights of action. You don't have to convince anyone in the government to enforce, you can go to court yourself against a website.
However, since AFAIK most of the bill only targets foreign websites, you can't go after Facebook or YouTube. You could wait until someone uploads a torrent of your material to ThePirateBay, however...
And then requesting that those sites be taken down. Let loose 4chan and the absurdity of the whole thing will become clear.
