Today, while visiting a large company, I tried to visit some of the websites on this site’s link-list. I found that three of them were blocked due to “possibly inappropriate content.”
The three blocked sites were Eszter Hargittai’s blog, Arnold Kling’s “The Bottom Line”, and Donna Wentworth’s “CopyFight”. (The whole Corante site, which hosts several blogs besides Bottom Line and Copyfight, appeared to be blocked.)
My hosts told me that their company uses CyberPatrol to filter their web access. So apparently CyberPatrol erroneously blocks more than 10% of the blogs I read.
