A List Apart strongly opposes United States H.R.3261 AKA the Stop Online Piracy Act (SOPA), an ill-conceived lobbyist-driven piece of legislation that is technically impossible to enforce, cripplingly burdensome to support, and would, without hyperbole, destroy the internet as we know it. SOPA approaches the problem of content piracy with a broad brush, lights that brush on fire, and soaks the whole web in gasoline. If passed, SOPA will allow corporations to block the domains of websites that are "capable of" or "seem to encourage" copyright infringement. Once a domain is blocked, nobody can access it, unless they've memorized the I.P. address. Under SOPA, everything from your grandma's knitting blog to mighty Google is guilty until proven innocent. Learn why SOPA must not pass, and find out what you can do to help stop it.
