Laws like this at the national level? No, not according to the Constitution...Doesn't the Constitution mention something about regulating Interstate Commerce (Article I Section 8 to be exact: To regulate commerce with foreign nations, and among the several states...)?
I'm quite sure that all of the calls I get are not exclusivly from my home state.
there is already a way to get off of most mail marketing lists. see:
http://www.ftc.gov/privacy/protect.htm#Direct i don't know why they should charge you $5 for this, but it's something you can do if you're truly ticked by junk mail and it is the industry making an attempt to regulate itself (no feds that i can see).
as to the phone calls - if they didn't use computerized systems that dial every freakin' phone, maybe they wouldn't be in this mess. have you ever been in an office with consecutive phone numbers as one phone after another rang w/these stupid calls?
i pay for an unlisted, unpublished number and still got these calls (because of the computer dial system). even if you tell the salesperson not to call you, either they aren't in control of the list or they don't care. all i know is that it hasn't worked for me.
what seems to work so far is getting the phone number blocked. i did this about a month ago and can't think of any telemarketers calling, other than those w/whom i already do business.
