First of all, let’s look at the purpose of SOPA and consider what it’s intended goal is:
Taken from one of my favorite sites, Wikipedia, ironically one that would be blocked if SOPA was enforced, here’s a definition of what it is:
User-content websites such as YouTube would be greatly affected. Concerns have been expressed that they and many other similar sites would be shut down if the bill became law. Entire domains could be blocked if something was posted in a single photo, video, blog, article, etc. Taken to extreme, practically any website on the Internet would be infringing due to their content.
