Accusing another speedrunner of cheating is a serious accusation, that should not be thrown around lightly. The burden of proof is on the accuser to prove reasonably that the speedrun was cheated after it was already verified. If you are referring to the run that was discussed on the discord, it does look suspicious due to the jump of the mouse, however this could simply be the video recorder skipping some frames due to various reasons. I am looking to bring this matter to the attention of the other mods, but given the circumstances a snap decision should not be made before the run is carefully analyzed. depending on the results of investigation the run will either stay, or be removed promptly.
