I too am on some kind of a list because every day I get calls from random numbers. This one called today. So, I did what I've been doing to all of them: I picked up the phone, pressed PLAY on this sound file:

And hung up. It seems to be working, so far the numbers I use it on don't call back. But, I'm sure the list I'm on is sent to DOZENS of scammers and telemarketers, so it will probably be a while until these calls completely stop. Your best bet is to put in fake phone numbers for anything you sign up for online.
