The other option is to risk being put on a blacklist for running a 
non-compliant mailing list.

Forget spam. A mailing list that does not require a response to a 
confirmation before subscribing an address can be abused for a DOS attack. 
Suppose I don't like you, and decide to subscribe you to 1,000 mailing 

If they require confirmation, you get 1,000 confirmation messages and it is 

If they DON'T require confirmation, you are now on 1,000 lists that you need 
to track down and unsubscribe from.

Explained this way I've yet to loose a mailing list customer.
