I just found this tool which seems to be the best to look into the
history and easily see who deleted the members from the relation and
what happened to the members.
http://osm.mapki.com/history/relation.php?id=7227 -> click on member ->
http://osm.mapki.com/history/way.php?id=23273022 -> all nodes deleted by
the same user who removed the way from the relation. 

The user seems to be in good standing so they probably missed the
validation step before uploading to remove the empty relation.

I encourage you all to pick a few relation from the list and contact the
concerned user in the changeset so that they can remove "their" empty
relations from the database. JOSM ask with a dialog that might affect
users "do you really want to remove this relation - it cannot be undone"
which might be scary to contributors.
