But they don't. Bad guys routinely control zombie farms of 100,000 machines or more. People I know who run a blacklist of spam sending zombies tell me they often see a million new zombies a day. This is the same reason that hashcash can't work on today's Internet -- the good guys have vastly less computational firepower than the bad guys. I also have my doubts about other issues, but this one is the killer.
