If I can't recommend my own name then I'd recommend
Amitabh S
He was one of the first guys I interacted with and someone who's actually polite and incredibly knowledgeable of crypto.-edit-
Damn I should really read up on what happened & the people involved .. just read this..
The private keys were held by CSO Amitabh Saxena and the company has filed a case against him, his response to the way in which the funds are hacked are just flimsy and i do not think Benson has anything to do with the loss and the company has ensured that they will be crediting its users, it is a really unfortunate situation and with him being removed as the moderator i hope the local board wont be a junkyard.
-edit-
If a new mod is picked, it should be someone from 2012 - 2013 era..

Being the moderator means someone who's the defacto leader of that community, Benson is perfect for that role because he listens, he's been busy and slightly less active here but set that aside I don't think someone can actually replace him.
But a second moderator to assist him? THAT surely can happen.
