Unless I'm missing something (I've watched it several times) I do not see any way of us knowing what player this is. The playername that you reported does say in chat that there is a speed hacker on the ice, but we have no way of knowing it was him that was doing it. I am going to close this for lack of evidence, however if I have missed something, please report again and let me know.
Thank you for the report. Unfortunately the evidence provided is insufficient. Should you gain more evidence in the future, do not hesitate to report this player(s) again. Kind regards, The Staff
