Hello, I understand what your saying. What probably happened is I marked a  a couple fairways using a line instead of an area. I have been mapping courses now for over 4 years all over the world. I know there have been issues in the past with other users deleting features around courses that should not be touched. I will always ask the person what is on the course that I can see because sometime OSM and google maps really are horrible is showing features. The clarity sometimes are blurred and you can only guess the outline of fairways, bunkers, tee box etc. 
However I do respect what you are saying and by looking at some of the pics in the description that is exactly what I do.
Have a great day :)
