I’ve made a map (well, written an Overpass query) that lets me quickly see in which areas POIs might need re-checking. I know there are already a few options but I wasn’t really happy with any of them.
It looks for check_date
first and if it isn’t set, looks at the time the object was last edited. It uses the same list of objects (shops, cafés, restaurants…) as Every Door.
Yellow dots are POIs that haven’t been checked in over a year, for red dots it’s been more than five years.
