The do not email registry you are suggesting is prone to abuse (by anti commercial email advocates, rouge affiliates, and potential competitors to a certain product), can be easily attacked (what if an email virus triggers an unsubscribe request, or a competitor decided to attack another company by triggering do not email requests using forged emails), and is totally unworkable (what if a person just wanted to opt out of the mailing in general simply because they don't like the author, but not the products advertised within?). Add to that it violates privacy rules of most mailing lists (they promise not to share their mailing list with anybody, now that email must be given to others "for their own good"?). It is for these reasons I urge the FTC to ditch the do not email registry or any form of supression lists.
