Apparently my blog is blocked on a federal government department's network as "Category: Pornography/Sex,Entertainment (Global)".
Besides the mis-categorization, it just goes to show the futility of filtering web sites based on the URL or domain. Kristy read my blog via some kind of aggregation, probably one of the planet aggregators on which my blog appears. Handily side-stepping the classification.
Kristy is being coy about which government department, probably for good reason, but I'd love to put "As classified Pornography/Sex,Entertainment by the Department of..." on my site.
