No proof there
Could be anyone
and doesnt show any score either
Theres 2 clips and the first clip guy does 2 laps, the other clip of the 3rd place guy he does 1 lap…simple basic common sense, first it’s “you need videos” now you want even more 
get serious dude, just accept the fact that people cheat/find the glitches to get top scores and youre now upset because i proved my point
It is a bit curious how the first two guys on Limerock have a much higher score than third place. After that it’s pretty consistent.
After watching a couple of replays, it does appear that the first place guy is doing multiple laps while everyone else has one. Still though, I’d say that it’s more likely the game having server glitch issues than someone cheating.
