Here's an article from the most recent edition of Reader's Digest (yes, I read Reader's Digest - the jokes are hysterical) that discusses how ripped-off consumers are getting back at shady companies.

Pushed over the edge by one telemarketing call too many, a justice-seeking vigilante decided to get even with his auto-calling tormentors in 2009. Auto One Warranty Specialists was the target of our hero's righteous ire. The still-unidentified citizen was being bombarded by unsolicited robocalls from the Irvine, California, company, which was trying to sell him an extended auto warranty.

Rather than slam the phone down, he stayed on the line long enough to jot down the company's phone number. He then posted it on the social news website reddit.com, urging fellow frustrated call recipients to give the company a dose of its own medicine.

Soon disgruntled customers and Internet crusaders were flooding the company's phone lines with junk calls, elevator music, angry rants, and even Rick Astley's cringe-inducing 1987 hit song "Never Gonna Give You Up."

The outcome: The deluge of calls overloaded Auto One's phone lines. Even the Missouri attorney general jumped in. Last December, he sued Auto One's parent company, Credexx Corporation, accusing it of robocalling people on the state's do-not-call list. The company agreed to pay a $75,000 fine to settle the suit.
