Deletion of List of flight schools

Comment: The nomination (and therefore any "per nom" delete opinions) is flawed in that it is based on what the nominator fears what might happen to this list rather than what it actually is, which is a work-in-progress (as are all of our articles) list of notable flight schools, which clearly serves a navigational purpose, per #Navigation. Many of our articles are spam magnets, but we have ways of dealing with that problem such as watchlisting, blocking and (semi-)protection, rather than throwing the baby out with the bathwater by deleting articles
