A few weeks back I mentioned the COICA bill that I referred to as being worse than ACTA. Well, they're getting ready to start voting on it. This is the start of censorship on a huge scale and if you think they'll stop at copyright infringes, I envy your naivety.
A Petition is here, though I would also recommend contacting your congressmen directly and letting them know that you won't stand for something like this. This is supposed to be a free country...let's try and get back to that.
