E2 4. If an email is forwarded to a friend, no opt-out mechanism should be required. Do not email registry - this would place an undue burden on small businesses. A requirement for merchants to maintain suppression lists would have a drastic unfavorable effect on legitimate businesses, especially small one. There are so many problems and costs associated with this idea, and so much damage done to consumers and businesses alike, that I urge you to abandon the idea. Requirement of the use of suppression lists will seriously damage many of the legitimate publications available through email. There's also the potential for significant harm to consumers, because of the problem of properly knowing their intent when they unsubscribe from a list - they may be doing so temporarily e.g., not because they never want to receive anything from that publisher. On top of that, these suppression lists could easily fall into the hands of spammers, leading to more spam instead of less.
