The down side with negative IDs is you can't track them in any way
once they're upload without getting the new IDs from the person that
uploaded, or guessing at map objects, in the case of Haiti there were
a lot of objects tagged with similar information and if the lat/lon
changes between revisions you'll end up with duplicates in the system.
