I here Local Club's and AMA e-mail lists are being bought and sold by old and new companies. Wonder if this is where some of this problem is coming from.
Turn about IS FAIR play!
Get at sites by Listing them as YOUR e-mail site. Fill out information of the bad business e-mail and web sites, to other companies as your own e-mail and or web sites and let them get there own e-mail address passed and sold to themselves and see how they like it.
Get a data base going with the compaines that send you this junk and spam, then pass there junk right back to them and others in those same business pratices.
