Even if there is something going on, the problem for this coins dev now is credibility. Even if he were to come back and start posting again, with the excuse he had been kidnapped and tied up in a terrorist detention camp this last few weeks, no-one is going to take him seriously even if he were to provide date stamped photos of himself in said camp. The general consensus would be that he is only back to pump the price again so he can do another dump. Trust takes a long time to earn back once its been lost. The network hashrate on this coin is 58mhs. Even if there was someone with insider knowledge buying these coins up, he would also quite likely have some hardware pointed at it to sustain the network. As it stands, I could the fork this coin all by myself if I wanted to.
