Philip Berne:

I stopped downloading any pirated content about 5 years ago, when I was caught and sent a nastygram by my cable company. But it wasn’t really the cable company who caught me. It was HBO. I was trying to download The Wire. The warning I received said they were not pressing charges immediately, but they wanted me to stop and destroy my copies. They also reserved the right to sue me at any point in the future. I’m probably in the clear, but hopefully this screed will go some way to convincing HBO that I’m completely on their side. I have seen the error in my ways.

I bet that would be enough to make anyone stop illegal downloading.
