@MapComplete @mapcomplete_edits yes, I explained to them what was wrong, I hope they registered with an email they read, I also sent an osm message to them. Do users get a notification on Mapcomplete about osm messages?
I already fixed their similar changes some weeks ago, I thought they will be a hit and run type new user. Now it was 1300 changes, it seemed too much work to fix it one by one.
