Why am I doing this on a religious blog? The reason is that the SOPA and PIPA rules will allow anyone to get an American court order to take down a site for copyright violation, even if that violation is in a comment left by someone else. This means they can remove any .com or .org or other non-national address from the internet, leaving people in the rest of the world with no recourse unless they can afford to go to America and appeal the decision. They can also force search engines not to list sites, and service based in the US like WordPress to remove sites. Since contesting this wll cost money, it is quite likely that most actions will be unopposed.
In the past religious groups have used copyright law for monetary gain, to keep secrets, suppress splinter groups, and most worryingly to avoid criticism and debate. With SOPA in force if someone didn’t like a comment on a blog they could apply for the site removal. Very possibly the first a blogger would know about it is when the blog disappeared. If the blogger did get any notice it could well be a message saying “Turn up in a court in New York, Honolulu, or Anchorage if you want to object”.
I will blank this site out tomorrow before I go to work and enable it again at 20:00 gmt. I would urge other bloggers to do the same or at least put a notice up.
Edit: As others pointed out WordPress provided its own blanking option. Since I had already posted the times at which I would block and unblock my website I decided to use my own.
