Bah... the scoffers! If it's not anonymous, we could sue Blubster right? As for it being a "sting", the stings were done individually (one on one) and not through the net. If it is a sting, I would think someone with knowledge would leak it. Blubster's been around for quite a while and this particular version has been in development for a while now.
I'm curious as to the outcome of the people that are getting sued. I don't think they have a case since they can't prove who was using your PC or connection for the file swapping. Were PC's confiscated?
