Prosecuting Spamming Crackers?

lnixon asks: "As a recent Slashdot article mentioned, the latest trend in spamming is to use cracked Windows machines for sending spam and hosting spamvertised web sites, 'spacking', as Wired terms it. A couple of weeks ago, I started tracking one of these cracker rings down, carefully documenting the trail as I went.Mostly through luck, I actually found the originating server. This information should seriously put a crimp in their activities...if only I could get the law interested. I have tried to get the attention of CERT, of FBI and of my local police authorities, but nobody seems to be interested. Now, what should I do? Organize a posse?"
