In my city (Belo Horizonte, Brazil), there some guy with updates and change reviews supervisor credential or something like this, but withou any sense.
All of changes I suggest, was based in the real conditions and updated locations and directions in streets.
But he denied all changes... all based in old aerial photos, returning all to old geometri and direction (what does not correspond to actual reality).
If he, at least turn on "GPS POINTS" in update maps, he will see that all I change, was real and many many people walking throught my path.
Not only my changes.. anothers friends tell me the same thing, about the same supervisior in differents regions of Belo Horizonte... including denying delete of streets that not excist anymore.
I understand that credentials are adquired with points of contribuition, but, if the user can't verify if related or updated changes are not real, or if he can ever use the GPS points to verifing the news diretional and geometrical changes in roads or streets, he's not doing a good job.. he is slowing down many good contribuitions would do waze better.
