I've heard that [urban legend] cable companies send out 'commercials' that legally paying customers systems filter out. These commercials are for customer appreciation
giveaways. Sometimes it's a t-shirt, or maybe tickets to the movies or something. Anyway, it directs you to call the cable company, and you give them your name and address, and they know that the only people who can see these commercials are people who have these unauthorized descramblers, and they fine you, or throw you in jail, or beat your dog, or something.
I know this is true because a friend of my brothers cousin said his neighbors uncle had one and this actually happened to him. (sorry, I had to throw that in there
) [/urban legend]
