He is a merit source? Do you have any evidence to prove that he has been misusing his source merits?
Who has given him more than 11,000 merits other than other merit sources? Why don't you consider them "tricked", shouldn't sources read a post in full before meriting someone? And why didn't anyone notice his "manipulation" tactics before giving him so much merits?
I will not judge anyone here, but if someone takes advantage of a community by manipulation and deception, deserves no respect and should not be put in a position of authority.
Also note that, back scratchers are every where, it's not limited to this case, almost all merit sources discriminate when it comes to meriting.
