Well every new instagram guy in hollywood falls for the Mark Mendez aka MCMpix or marqnwmmgmt. Goes all the way back to Alex Valley, Michael Dean, etc. and even before that really. Sets them up with the nice meals, easy photographers and rich friends. He gets a good pay cut when they get blown and he gets to watch or even do more. They stay with him for a bit and leave after he can't do anymore for them. Rinse and repeat.
As far as this Darrell guy, he's the next Gage Gomez. Doing some heavy lifting clout chasing in the city if you follow his Instagram.
