The situation in this town is a little special: there is currently a new group of users who have been asked to edit OSM as part of a class.  I suspect many of them use iD on their phones.  That would explain why there are so many dragged nodes in their edits; I guess that users are trying to drag the map and do not realise that their finger selected a node by mistake.  It looks like they had their last assignment today, so we should expect less damage from now on.
