Your motive in taking someone else's name was...?
If I were a top player, I would be changing to other players names all the time to see how the enemy changes their strats. Playing as Luvnest may tell the other player to watch for snipers and multiple P4s for instance. But it will be Kimbo instead, so he will do something else. That is good for everyone. DONT MAKE ASSUMPTIONS ABOUT THE ENEMIES PLAYSTYLE.
It is also a moot point since ALL top players will check the STEAM page of the enemy and know who it is. As Kimbo stated, he did not change his Steam page so players would know it is him.
So name alone seems a little heavy handed to me. I am not commenting on Kimbos personal situation. It sounds like their was much more involved.
