[OSM-talk] Data reconciliation. Removing CT/ODbL declined users.

One *BIG* note that needs to be put out there specifically for the US:

User balrog-kun has explicitly declined the license. He ran a bot that
expanded abbreviations in TIGER street names in the western US which
means that virtually every named street west of the Mississippi shows
up as "tainted" in P2.


He has explicitly stated multiple times that he intends for these bot
edits to be relicensed under ODbL. So if balrog-kun is the only
declining user to have touched a road, there is no need to replace it.

The "ODBL coverage" map ( http://osm.informatik.uni-leipzig.de/map/ )
takes this into account but P2 does not. I think the map assumes any
change made in a changeset with a bot=yes tag can be relicensed
although I'm not sure on the exact implementation.
