The PROBLEM and the SOLUTION
I feel that part of the reason we have too many rejections is greed, hear me out:
We want agreements, it improves our wayfarer rating and gives us upgrades.
We want as many as possible in as short a time as possible.
We know that there is currently a problem within the community and it is rejecting too many good waypoints.
Combine all of this with the fact it only takes 3 clicks on a computer to reject a waypoint versus 10 or more clicks to accept a nomination and you can see where the problem comes from.
The system needs fundamentally changed so that reviewers must put the same effort into rejecting a wayspot ac accepting one, explaining why it doesn't meet the criteria.
