Make a complaint about a corporation online, and they will hunt you down and kill you. (Old news, but new to me:) eWatch provides companies reports on what's being said about their companies on-line. While most companies are using this just to gather feedback, many use it to retaliate with "reeducation" programs, one-on-one "customer service" to change the customer's mind and get them to reneg the comments. Some use the service to shut down negative web sites and coerce message board owners to delete messages, sometimes, given the opportunity, with the assistance of police.

Northwest Airlines used eWatch to track down the employees who organized a "sick-out" that almost shut down the airline last Christmas. After having fired the "perpetrators," a decision upheld in the courts, Northwest is now using the service to target angry customers for reeducation.

The above-linked article was published last July, appearing in Business Week's "best of" last week (whatever). See also their interview from last March with eWatch vice president Nancy Sells.
