Aye, another good review is...
WTF is SOPA ? aka The American Government trying to ruin the internetTotalHalibut; He's a British National, and even he is concerned! That should say something, as the U.S. sets the standard for Freedom all over the world because we're basically the only Country with Freedom of speech (From what I know), among other freedoms such as life!
Websites that would be blocked off of the top of my head:
Multiple forums (Maybe even this one)
Youtube
DeviantArt
Multiple file sharing websites (Mediafire, ect.)
Anything that they don't like
Anything that could POSSIBLY (Yes, only possibly) enable copyright infringement
Google and other search engines
Now, this is basically killing every outlet of free speech in the world; We MUST stop SOPA and PIPA (The bill going along with SOPA) from passing! Even if one of these gets through, it's going to make our lives a living heck.
Stop these bills!
