There are lots of groups that accept spam complaints, and they usually don't charge the complainants anything for their service of cracking down and eventually blocking those damn spammers from continuing to practice direct marketing systems to those unfortunate spam victims. Unfortunate my ass, you bunch of losers! Complaining to these damn groups usually takes years to see the results, and their actions are often too damn slow you'll end up having more
spam messages than the crapload of spam mails you had even before you got to know these groups. It wouldn't even make much of a difference even if you end up complaining to the government, you know!
