The San Francisco Bay Guardian

Has Spocko's story:

For the better part of a year starting in late 2005, San Francisco blogger Mr. Spocko waged a quiet campaign against right-wing talk radio station KSFO, 560 AM. He wrote to its sponsors and played for them explicit portions of the station's programming, such as shock jock Lee Rodgers's call for antiwar protesters to be "stomped to death ... just stomp their bleeping guts out."

The idea was to educate corporations about exactly what they were sponsoring, in the hope that Spocko's work might staunch the free flow of hateful rhetoric.

They handle the story very well. Go Spocko!
