I don't agree that competitors who BO should be banned. There can be many factors contributing to a BO, including stress, pool too cold/warm, certain foods and drinks, tiredness, previous exercise etc. These can't always be anticipated - if the competition pool or surrounding area is extremely cold or warm, it is unlikely anyone would have known this in advance.

Banning competitors who BO assumes that all BOs are caused by unrealistic performances, but they can be caused by many other factors. If someone is blacking out repeatedly in competition or training due to excessive performances or incorrect technique, I think they should be advised about this, and eventually banned if the situation becomes unacceptable.
