you must see both sides, following your theory, spammers stay away but good guys *are* coming back, greylisting is at the end the same only a little bit less stupid than this anti-spam-send-and-ask-a-confirmation-mail things also that spammers don't come back is an illusion, firstable they do it for money and secondable if they don't come back from the same source they come back from another and either one might be spoofed so you can greylisting yourself to death because sooner or later all sources are blacklisted or you're rewriting continuously your whitelists and both are probably unreliable at the end -- João A mensagem foi scaneada pelo sistema de e-mail e pode ser considerada segura.
