Even if he's merit source (which I doubt if he is), he's clearly not distributing it fairly.
Good catch! I'm pretty sure some DT members will read this thread and show their concerns
those three posts merited by him don't look like superb posts deserving 50 merit
and you should investigate more on the other user, chronicsky, who gave a whooping 50 merit on a single insignificant post
the problem is they, cryptoheadd and chronicsky, have accumulated quite high number green trust
Timelord2067 suspected chronicsky to have a few connected accounts, he might need to update the list
