All About SOPA, the Bill That Wants to Cripple Your Internet: “What the bill can’t do is block numeric IP addresses, so you could still access Lifehacker, or any other site that could be censored, if you knew that address. This is important because it means this bill can’t do much to stop downloaders of pirated content. If a domain name is blocked, everything will still work via the numeric IP address. Basically, the bill will be no good at stopping piracy—what it was apparently designed to do—but excellent at censoring any web site capable of providing its users with the means of promoting pirated content or allowing the process. This includes sites like Facebook, Twitter, YouTube, Tumblr, and many more.”
