First of all good work machan.
But one tip to you. Never ever post how you got him and how you managed to take the info. Because most of other lamers looking at this too. So they learn by the mistakes. And even if you fooled him never say that to him. Never tell what you did and how you got info. Anyway nothing much exposed. He was just fooled by talking so no worries.
Those days i used to tell those nasty people how i managed to track them down and tell nicely not to do that again. They just laugh and correct their holes and doing it again.
You can see this guy also never learned any lesson or admited his crime.
He said sorry in elakiri coz you blackmailed him saying you will post his info.
He surely now thinking of a way to bypass this and do something again. Next time you can't talk with him and fool him like this.
But there are tons of other ways to track him down so no worries.
