Qualification controversies
Elizabeth Swaney, who represented Hungary, qualified for the Olympics using "a loophole", by attending many World Cup events and just finishing the runs without falling. This has been called a "mockery" and her being labelled as a "scammer" by some people, while being seen by some people as "[a person who has] put in the time and effort to be here" by others.
