I regard most blacklists as broken too. They variously allow vindictive forgers to DoS people, or harm innocent customers of a slow-to-respond ISP without giving enough details for the innocent customers to "encourage" their ISP. They're useful input to scoring systems, but postmasters ought not to use them to refuse email, IMO.
