There is always the possibility he is telling the truth about his account either getting hacked or being used without his consent but only he can explain why he is trying to save the banned account when the account served no purpose. He is not exactly a prominent, overtly-liked or trustworthy member of the forum that he would be logging in to read and reply to a litany of PMs therefore why he was logging in to the (now banned) account regularly but was not posting remains a point of speculation.
