My view Cuz is that 100% was LKM.   The time taken to put on right avatar and sig, the fact that he would bother coming here in 1st place, his rather poor attempts at acting smart, making 'cute' remarks after comments aimed at him.  To me it fitted his profile, little doubt in my mind there.   And of course the picture of Raaj Deep, totally how i had visualised LKM.
