Aside from D3V's rule-breaking: MJ will not be back due to D3V's actions (at least not for perhaps years to come, if ever), and GravitonSurve (who was arguably driven off by D3V) will most certainly never return. !K_A! returned, but others have threatened to leave because of D3V.

It is a fact that D3V has been a contributing member in several ways, but what makes you think he will not repeat his actions and destroy the rest of the community? He is the only contributing (i.e. human) member I have banned since LiveWire.
