As long as we eat our own dog food, we should be able to locate these problems, albeit not in a timely enough fashion.
If those new users get it wrong, help them like you would any other new user. Keeping in mind they have: decent smartphones with GPS, heaps of time to spend either on PoGo or possibly on something more worthwhile like OSM. Tell them about Mapillary and OpenStreetCam. I know the game doesn't like to "share" the phone, but some people manage to kick their addiction (and hopefully swap it for a more useful one :-) ) Polyglot 2016-12-28 9:20 GMT+01:00 David Kewley <david.t.kew...@gmail.com>: > I've so far simply been using a basic query like > > highway=footway and newer:"2016-12-22:00:00:00" > > > This still requires a lot of manual review, of course.
