A lot of spammers are actually victims themselves, just your normal mom and dad that dont know anything about computers period, they end up with viruses, those viruses turn their pc's into another additional pc in Botnet attacks. Those that control the Botnets are the REAL Spammers. And a lot are in other countries. The spam rates in the USA are high because of the number of PC's we own and number of completely stupid people as compared to other countries, where by a lower percentage of stupid people own computers.
