We were told that we have to pick something from the first four reasons in order to reject a nomination:
We tried to tell Niantic that people would start using “Generic business” to mean “generic” when they put that rejection reason back in the current review flow and took out “Does not meet criteria” as an option. And the suggestion was made to the ambassadors which they relayed that something like a lamp post could be rejected as not “Distinct,” so that is how I use it. Reviewers are doing the best we can with the rejection reasons available when a nomination does not meet any criteria for acceptance.
