And people wonder why we worry about plans to censor websites. Every time it happens, the censorship ends up being much broader than planned. The latest example comes from Argentina, where a court order to block two specific sites -- leakymails.com and leakymails.blogspot.com -- actually resulted in over a million blogs being blocked
. That's because some ISPs, in order to cut off the blogspot site, simply blocked the IP address 18.104.22.168, which is used across Blogger's blogspot offering. As the EFF notes:
IP blocking is a blunt method of filtering content that can erase from view large swaths of innocuous sites by virtue of the fact that they are hosted on the same IP address as the site that was intended to be censored. One such example of overblocking by IP address can be found in India, where the IP blocking of a Hindu Unity website (blocked by an order from Mumbai police) resulted in the blocking of several other, unrelated sites.
