(NOV 16) Today, Congress holds hearings on the first American Internet censorship system.
This bill can pass. If it does the Internet and free speech will never be the same.
Join all of us to stop this bill.
Website Blocking
The government can order service providers to block websites for infringing links posted by any users.
Risk of Jail for Ordinary Users
It becomes a felony with a potential 5 year sentence to stream a copyrighted work that would cost more than $2,500 to license, even if you are a totally noncommercial user, e.g. singing a pop song on Facebook.
Chaos for the Internet
Thousands of sites that are legal under the DMCA would face new legal threats. People trying to keep the internet more secure wouldn’t be able to rely on the integrity of the DNS system.
