Cox Using Wardriving To Shut Down Customers?

Interesting thread on netstumbler.org -

I just got off the phone with a good friend of mine in the mobile IT business. He had a client today who had their account suspended without notification, after a call to Cox support he was told that the customer's account was disabled because of an 'open wireless access point.' After some further questions he found out that now have vans driving around in various customer areas throughout Orange County and San Diego.

Anyone else heard of this going on? What are the implications of this? Is Cox connecting to customer networks without their permission or just scanning to see for a AP without WEP? What are the chances of Cox turning off a customer that has an AP (without WEP) powered on but not connected to the net? What is the deal with not telling customers they have been turned off and still billing them?
