(for the benefit of anyone looking at edits by this Facebook mapper):
There's some "unclear sourcing" at the very least in there - for example, osm.org/way/1355696177 has added "surface=paving_stones" with "source=Bing", but a glance at the Bing imagery in iD shows that the alleged pavement surface is entirely obscured by a large building, so clearly that imagery is not the source of that tag.
