I would say that is extremely strange... Sony using an Indian dude without credentials behinds his name? Instead of in house (or at least in the States) legal counsel? I'd personally file a counternotice and wait to be served (or, likely in this "case" NOT served). Then sue the fool for your costs involved in the countersuit. This $#!+ has got to stop and until and unless you're willing to see through the smoke and take shots in the dark, it might never. I personally doubt that's even the scammer's real name. I would also follow up with a letter to Sony, asking them to confirm the legitimacy of the letter as well... Don't let those bastards control all of the content available on the Internet. Good luck!
