Thanks for the hard work! I wonder if a monochrome version of the logo would stand out better against the map colours?

Sorry to hear that. 😟 It must be a pain to clean up.

Perhaps editors under a certain edit count should not be allowed to edit fundamental map features. Wikipedia already does something like this by protecting certain controversial pages that are often subject to vandalism or edit wars. I’m not sure how this would be implemented in OSM, but as more and more people become aware of OSM’s reach, there is the possibility of more problems like this emerging.
