With all due respect this reads a lot like "curators good, nominators bad" which I feel like I hear a lot but don't find helpful.

A lot of rejection might be avoided if there were guidelines as to what Medium are asking Curation to accept. What you're looking for, not looking for. If you don't want literary fiction then own it, if you only want bland or only want sensational then own it, if you only want poems about x, y or z then let us know etc etc.

We can work together better if everyone has the same information.
