I am fairly certain its not him.
I say so, because despite his disgusting tactics, good ole' jonb knows
exactly what he is selling and this guy in that auction clearly does not. Jon's MO is to way overstate things conditions and their rarity and then not deliver what he is supposed to be selling. Rarely do you ever see such wild misconceptions as they appear in that auction like:
THESE TWO BOOKLETS WENT OUT OF PRINT THE FIRST YEAR THEY WERE PUT OUT ON THE SHELVES AND WERE COSUQUIENTLY PUT OUT IN MULTIPLE PRINTINGS 2ND PRINT TO SIXTH PRINTINGS
Jon loves to say things are RARE!! and HARD TO FIND!! that clearly are not rare or hard to find, however he would never have listed that M&M book as a 1st print as he would know that its obvious to everyone who knows anything that it is not a 1st print and so it does not make a good con. Jon is also literate enough to make his auctions readable and they were written like an educated person which is why he is a good con man. This auction is littered with gramatical errors and spelling mistakes and it looks like it was typed by a homeless person who flunked out of elementary school...or then again perhaps Cougarrinard, same difference.
