What this bill would basically do,would be to block sites with even a claim of copyright infringment.
Let's say for example,someone uploads a photoshopped image of MLP:Friendship is Magic to a site like Deviantart,and others learn about the art theft and start reporting it. Under the law,if there is even a pic of art theft on a site,it would cause the whole site to be blocked. There is no due process. Like go to a site like Ebay and see how much pirated stuff is on there from China.
