Blocking/unsubscribing people based on their email provider seems... sort of impolite or unwelcoming. A greylist could work.

Greylist, as in temporarily refuse a message, and wait for the sending mail server to retry?  I don't see how it would work against hijacked hotmail accounts, they most likely use the real hotmail service - which would retry appropriately.  My own experience indicates that spammers now often "correctly" retry deliveries, so greylisting is less effective than it used to be.

Given the relatively low volume of spam, my vote is for the original suggestion of first-message-moderated, with the ability to put an address back on moderation if their account is hacked.

I see greylisting as specialised form of moderation: * If it's a new user and they send spam, kick them off the list. * If it seems an existing user has had their email hacked, give them more than one chance before kicking them off the list, possibly sending a message to them directly to check if they are still able to access their account and stop the hijacking. But +1 to at least moderating new users; I'd prefer something more concrete for dealing with possibly hacked accounts than just "moderating" them again. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
