i read an interesting point some time ago
some guys collect millions of email addresses... some real, some phony, and spam them with some bullshit
they'd also include a "click here to unsubscribe" link
whoever clicks the unsubscribe link would be added to a "good" list by the spammer --- a list of addresses that the spammers know are valid and (99.99% chance) read on a regular basis. hence those unsubscribers would be spammed even harder.
of course these guys were opting OUT, so i don't know how useful their email addresses would be.
sasush, i'm looking in your direction
