YES!
I got a letter from them the other day that pissed me off no end.

"YOU ARE BREAKING THE LAW BY WATCHING TELEVISION WITHOUT A VALID TV LICENSE" was how it started.

Not "You MAY be breaking the law", but "YOU ARE BREAKING THE LAW!"

Feck off. If they ever come round, they're not coming in on principal. I don't have a TV (well, I do, but it's not plugged in), but I still want to see them waste their time and money on getting a warrant and an accompanaying police officer to come round.
