Or like the stories of people who worked out a rhythm with their lesson teacher so that the people who "should" make the band play it at the beginning, and others don't?
Or the judge that puts his/her head down on the desk and takes a nap during the audition, then makes up scores? (I've seen it. In person)
I've heard and heard of all of those in my time in the classroom. There isn't any more cheating/unethical behavior going on in an online audition than there is in an in-person one - it's just different kinds of cheating.
