Why? Couldn't spammers encrypt the mail they send to you just like everybody else?

It'd probably become like SPF/DKIM - somewhat spammy companies who still have a genuine mailing list and will still opt you out if you ask (or even click 'Spam' in gmail etc via FBLs) will go to the effort to implement it, but random viagra spam being pumped out by botnets likely won't.

Because, I think, they would have to be part of the Key Directory too, listed under "Spammer".

This kind if implies a secondary directory market of ratings and rankings of the prime source (ie isASpammer, isWithinThreeHopsOnLinkedIn)

They'd just keep creating new keys, and use a botnet to exchange seemingly valid e-mails with itself and a trickle of seemingly legit e-mails (buy access to a few small legit mailing lists to make sure their botnet isn't a total island). It's not clear to me that this won't make it possible for spammers to manufacture/buy sufficient "trust" to put themselves in a better situation than they're in today.

Darn - I think you are right... Ah well, defeating spam is only a nice to have from this

Yes the could, but it would at least cost them more resources which could matter at the scale most spammers work.

AFAIK most spammers use botnets, so they don't really care about resources - it's not their resources to begin with.
