   HOT is actually working on a tool (Underpass) to find duplicate 
buildings in near real-time, so it will be able to monitor duplicates 
from mapathons pretty easily. It's being built into the Tasking Manager, 
but also runs standalone.

   The tech team is doing a lot of work these days on automating data 
quality, because it is a problem, and it's better to burn CPU cycles 
than brain cells. I know some areas in Africa with quadruple duplicate 
buildings all added by mapathons. :-( Many thanks to the unmappers!

   A lot of duplicates came in because iD didn't display buildings based 
on your zoom level, so people didn't know there was already something 
there. I also prefer JOSM with the building plugin personally.
