Another hypothesis could be, he doesn't want anymore to post messages on the forum or in PM either because he can't give some informations about what is going on with the platform and he is ashamed of the situation. If he was here, dozens of people would ask him every day to credit their missing WOFs and cashback from the Premium Membership program along with refund requests from the guys who have been phished with fake deposit adresses.
That could be one of the possibilities. After all, we have seen TheQuin solve almost all the issues he addressed which shows he is a person with morals.
Besides that, things started getting ugly as soon as he disappeared from the forum.
May be he didn't support what was coming in front of him and rather chose to quit.
