About this fellow, just saw that Pbmining.com's site is "under re-construction", let him re-build, I bet he or they've been scamming elsewhere anyway and sooner or later they'll hit a wall, I wish I could see that.
It's been under re-construction for a few months now. I know he tried to scam before PBMining with a fake Blockchain.info website so I don't think he'll be leaving the scamming scene anytime soon, until someone catches him.
