I honestly think same thing that happened to him is currently happening to those Dormtainment brothas.
They started around the same time, 2008-09, constantly cranking out videos and building a base. They were both passed by the Vine generation of stars (King Bach, DC Young Fly... etc etc), but still managed to work a deal with All Def Digital. Moved out to L.A., then bam... they go radio silent.
I believe DT is signed with Kevin Hart's company now, and they still do weekly podcasts but their videos came to an absolute halt.
