I'm not sure why they are allowed to just map things that no longer exists.  Every other user who maps things that don't exist anymore or map things poorly such that they cause KeepRight issues are told to stop by the DWG.  I'm not sure why this user gets a pass, despite damaging the map by mapping things for "historic" reasons.  The community and wiki seem to agree that only things that currently exist should be mapped, so the fact that this user has continued to readd non-existent features should be an issue.  I don't know what their issue is with not spending the time to put it on OHM where it can live on forever and they won't be bothered, but instead they insist it needs to be on OSM.

Hopefully the DWG and community can step in on that discussion to bring an end to the mapping of these troublesome issues.  Unfortunately, I can't get rid of it since he needlessly and carelessly reverts all changesets I do in NY, despite on-the-ground surveys and other sources to determine it no longer exists.  It doesn't take a rocket scientists or a 1st grader to know that there is no canal where this freeway is, or those buildings are.  So I don't know.  I don't know how to get it to stop or how to get the community to come together to enforce the "historical items shouldn't be mapped" principle.
