Althouse is censored by the IRS.

A reader who works at the IRS and has, in the past, read my blog from his computer there — on lunch break, of course — couldn't get through to my blog today. This message came up instead:

The Internal Revenue Service has restricted access to the requested URL.

Reason: The Internal Revenue Service's category "Phishing and Other Frauds" is filtered.

URL: http://althouse.blogspot.com/

By what process and what standard was my blog identified as a "fraud"?
