They already don't comply with DNC listings, so unless they actually start prosecuting them, I don't hold out much hope. I actually enjoy trying to keep them on the phone as long as possible, and if I can get them to the point that they tell me to F-off, I've won. Sites like fakecreditcard, etc can generate all the creds on the fly, and between stalling (someone at the door/another call), and acting like you can't hear them / understand, etc., getting them exasperated is cheap entertainment.

Well not talkin' bout me, I aint edjumacated !! If I screw with them, it's kinda if I feel like it, not like this is the path always taken....
