since I have "catch all" domains I find out who is selling my name by preceding the name with the websites name. For example if I signup at site xyz.com I make my email on registration
[email protected] so if I get spam on that email I know where it came from.
Just to reiterate RCU does not sell, give away, trade, share or disclose its mailing lists to anyone. If a vendor wants to reach our members they can advertise on the site or have RCU send an email out with our opt-in partner special deal newsletter but they never get a hold of any RCU member emails.
We realize that spam is a significant problem (we get 100's daily ourselves) and are part of the solution rather than part of the problem.
