angry tapir writes "Until recently, spammers were in an ugly war of attrition. As spam filters got better and better, spammers bumped up the volume of messages they pumped out. If a fraction of one percent of a million messages get through, that's not profitable. Make that a billion messages and the money starts to add up. But it now seems as though this war of escalation has subsided; not because the spammers have given up, but because the game is changing."
