Unfortunately, since the messages sent by spammers that "came into the light" (good spammers?) and by those who did not are so similar, even legitimate unsubscribe links are effectively too risky. Just like with the failure micropayments (see http://openp2p.com/pub/a/p2p/2000/12/19/micropayments.html http://openp2p.com/pub/a/p2p/2000/12/19/micropayments.html), it just requires too much mental analysis to make an educated guess about whether an unsubscribe link is legit, versus confirming my address as "working" and increasing its use by other spammers (e.g., inclusion in sold lists of "verified working email accounts"). Due to the confusion, I have to fall back on the KISS rule: When in doubt, do not provide my email address, or the fact that my email address is a working one, to someone I don't know (or who just spammed me, no matter how much "in the light" they may seem to be).
