They know that more will put there school as a first choice unaware of the results so they potentially get the best, it’s wrong and shouldn’t be allowed, it’s unfair of everyone else
I'm not sure exactly what you are saying?
The school will 'get the best' of the applicants who apply, because they admit on score (wirh priority given to those applicants living within a large - for a densely populated area - 'local' area). Those who are not ranked high enough in the second round won't get a place, wherever they rank the school on their CAF. Just like for a non-selective school where the main criterion is distance, you may know that you live 'quite close' to the school, but not whether few enough others don't live closer for you to get a place.
If you don't get your first preference school - however the school ranks candidates - it doesn't affect where you are ranked by any of your other preferences.
And if you intend to appeal for a place if you are turned down, however realistic your chance of success, you have to apply, regardless.
