What's your take on Yahoo winning their lawsuit against these spammers? They may never collect a dime, but they put a real dent in these spammers ability to continue their #@6!. LOL
These cases against spammers are so rare that being a spammer in today's reality is probably one of the safest professions in the world (legal liability-wise). I doubt this would scare off other spammers from continuing the activity.
Spam will die when it becomes unprofitable. And that will come when people stop falling for it.
