But it requires time for registering and in case of intolerable abuses
entire domains can be banned. I do not mean defeat all spam, I think
it's impossible, but if blacklists are quickly distributed and updated
spammers sending tons of unsolicited messages can have a hard life. It's
just a question of economy: you don't send spam if it cost you too much
in term of maney or work (that is money) if the benefit is too small ;)

If fact with IPv6 it will get even worse :/ There the only effective
method should be banning entire subnets

I forsee a problem. Such solution sounds like a version of Spam
Assassin for IM. But IM needs instantaneity and bayesian filters can
introduce load and delays in queues. Mail systems can afford such
delays, IM can't.
