You have a point there, however marcotheminer could request a change in ownership of the thread to any of the administrators so someone that is neutral (towards anyone, perhaps one of the moderators would be the ideal candidate) would be keeping the thread updated instead. But again the issue is, marcotheminer isn't active nowadays.
I would be prepared to administer the thread for a while if need be.
What I would do is browse the numerous pages to compile a list of all known Escrows, current or historical contact all of them regardless of activity (unless
Red Paint TM such as
master-p or
QuickSeller etc) to ask the simple question: Are you an escrow still? then post a summary of their response along with a link they provide to their Escrow OP and and fees stated.
Of course, someone could do this anyway and then weekly/monthly post their results on this thread regardless of whether or not the OP is active.
