could you please share the overpass query you used ? i'd like to review
such additions around here as well.
i am following the edits of new users, and so far contributions of 2 or
3 have been worthy a revert.

it would be also useful to have a list of tags/changes the pokemon go
players make. footways are the most obvious, but i've also seen
(incorrect_ recreational_grounds added. several users have also changed
existing residentials, pedestrian streets and tracks to footways -
incorrectly in all the cases.
