School District Told to Replace Web Filter Blocking Pro-Gay Sites; New York Times, 3/26/12

Michael Winerip, New York Times; School District Told to Replace Web Filter Blocking Pro-Gay Sites:

"The way it worked: the URLBlacklist filter classified gay organizations in the “sexuality” category. The sexuality filter also screened out pornography. As a result, when URLBlacklist filtered pornography, it also filtered Web sites supportive of gay causes.

On the other hand, antigay Web sites were typically classified under “religion” or not categorized at all and so were allowed through the filter."
