We don't know if OP is not a trust abuser, scammer or competitor of the accused user. People are doing all sorts of thing to make others look bad, especially if that other is someone they do not like for some reason.
None of that really matters as long as those sock puppet accounts provide legit and quality evidence that support their claim but in this case OP failed to do that (at least regarding ban evasion). As others said, just because they used the same address doesn't make them alts but I always wonder what could be the reason behind that and how likely is that they tried to frame Murat by using his address. Having said that, I think that there is a pretty good chance those accounts are his and that he is indeed ban evading, but impossible to say with 100% certainty without stronger evidence.
