If he was lagging, surely he would of said during the match? Also, I love how when Rick was going "why Muff, why speedhack, etc" and then Muff acted all innocent and went "?".. then, as in most hacking scenarios, Muff said "ns" to Ricks completely hopeless aim party against him, just to make Rick maybe change his mind a little?
But it's not up to the public to decide. I'm sure the committee/jitspoe will come to a reasonable decision on this.
