DTV tried that **** with me back in around 2005. I had purchased a smart card reader and they closed the site down with the help of the Canadian government. In doing so they also got the customer list.
One by one they went after everyone on the list trying to get them to agree to pay 10k in order to avoid them suing you.
I repeatedly told them card readers had more than one purpose and the fact that I own one and happen to be a DTV customer does not automatically make me guilty of stealing satellite services I don't pay for.
I told them **** off many times, during the harassment of multiple calls daily, a Virginia judge agreed with my assessment in a counter suit brought by other DTV customers in Virginia that also owned a card reader.
They still harassed me for several months after the ruling. But finally at some point they realized I was not going to succumb to their threats, they finally stopped.
All they have is intimidation.
