This is Dennis from the Data Working Group. We received a report that you are mass deleting map features which are done by on-site survay or local knowledge. By observing myself, there are some features you deleted that should just simply modify the existing features. Be aware that OpenStreetMap is a collaborative project, not a one-man project. Keep in mind other people's hard work should be respected, unless there are some mass modifications, and things removed, you should not mass delete stuff.
