Kevin Triebel: The Legendary Shitposter. Who was he?

I used to frequent Pixeltendo many years ago, when edgelords and shitposters were plentiful.  

Anyone here remember the Kevin Triebel spriter/shitposter? 

I've been gone for so long that I wouldn't know, but I'm just curious as to if it was ever revealed who he was? 
Was he a resident user trolling as many suspected? Or is this still shrouded in mystery?

Also, hello, to all my old pals from PT/tSR.
