The Stop Online Piracy Act proposed in 2011.
SOPA is the first of two bills being considered by Congress. The second is E-PARASITE/Protect-IP.
The bills are created to prevent piracy, copyright infringement, and block access to "rogue foreign sites."
While well-intentioned, the bills have been generally panned by the public and the major tech companies due to the fact that companies can get domains and websites shut down if they "engage in, enable or facilitate infringement."
By creating this blacklist, governments and companies can choose to get sites cut off from search engines and from accepting payments for ads. SOPA only gives accused websites 5 days to file an appeal before they get shut down.
SOPA will kill innovation. Please sign up here to fight it:
