There is a Postal Form ( I believe it is called 2000) for the return to sender at their cost of any unsolicitied materials you find offensive. What you find offensive is YOUR CALL. I did this to great effect during the last Presidential election. I always STUFF any prepaid return envelopes with as much trash as I can fit. Just obliterate any and all references to you. I doubt if their scare tactic about prosecution amounts to diddly anyway. As for telemarketers, remember, time is money. Unless you expect an important call, KEEP them on the line. Get stupid, ask them to repeat the information. Get personal. compliment their sexy voice( if it's a guy, talk about this terrific leather fetish bar you'd like to take them to.) Once you've tied them up for several minutes, just hang up.
