He HAD a manager. There were like 3 other guys that were a part of their little group.
Then things started getting weird with that guy when one of the creators (Dan Damage) tried to pull out of the deal, so the manager went on the other creators Twitter accounts and started a smear campaign accusing Dan of being homophobic.
That seems to be the catalyst point of when people started to drop out of their group, but the manager still maintained the rights to the content already posted. Hence why there were 2 Jimmy accounts. The former manager changed his to Luke Levis now.
