I dont see anything in this 27,650 video which proves that was the actual score achieved here. The score is unreadable for the entirety of the performance, then at the end when the camera is brought closer a score of 27,650 is able to be read, but nothing's to say it was actually achieved in this run, it could have been from a previous performance.
In addition to that, poor video quality and conveniently having the phone a number of feet away from the monitor is a good way to hide glitches or illegal tactics, as well as hiding strategies you don't want other gamers to know about.

I'm not accusing the submitter of anything underhanded, I dont believe that to be the case at all, Im saying this video should have never been accepted in the first place.
