Back in March, Facebook won an injuction against three spammers who sent unwanted messages and made abusive wall posts on the site. The temporary restraining order placed criminal consequences on their continuing actions, but the legal battle didn’t end there.

This week Facebook reported they’ve been awarded $711 million in damages by a San Jose, CA court against Sanford Wallace, the notorious ‘Sam King’ that MySpace also successfully went after last year to the tune of a $234 million judgment.

Seven hundred and eleven million dollars is a lot of money. But, it’s not the highest judgment levied under the CAN-SPAM Act, a piece of legislation that contains tough penalties for violations surrounding commercial email and message sending. That honor also belongs to Facebook, who in November of 2008 won an $873 million victory against Adam Guerbuez and Atlantis Blue Capital.

More than being about the monetary figure though, especially considering the difficulty of actually extracting the cash from the defendants, is the deterrent effect these judgments will hopefully have on future would-be spammers. Facebook implores its users to help stop the scourge by using the ‘Report This’ links throughout the site when you spot the evil stuff.

What do you think about the ruling and the effects it might have on other spammers?
