Hi,

Pokémon Go seems to have updated its OpenStreetMap data [1] leading to
an higher than usual number of new mapppers adding parks – some or many
of them are fictional. It is a good idea to check
http://resultmaps.neis-one.org/newestosm for your country (click on the
flags to show only edits from your country) and use Overpass API queries
looking for ways tagged with like leisure=park, natural=grassland or
landuse=grass which have been modified recently.


This might be a suitable Overpass query.

[timeout:120]
[bbox:{{bbox}}];
(
        way[leisure=park];
        rel[leisure=park];
        way[leisure=garden];
       rel[leisure=garden];
        way[recreation_ground];
        rel[recreation_ground];
        way[leisure=playground];
      rel[leisure=playground];
        way[leisure=pitch];
        rel[leisure=pitch];
        way[landuse=grass];
      rel[landuse=grass];
);
(way._(newer:"2018-04-23T00:00:00Z")->.w;rel._(newer:"2018-04-23T00:00:00Z"););
out geom meta;

here is overpass link with it: http://overpass-turbo.eu/s/yee (navigate 
to your area, click "run" and wait)


At least in my region detecting parks and recreation ground with 
untagged name state (without name and without noname) is useful to 
detect mistagged areas http://overpass-turbo.eu/s/yeg


[timeout:120]
[bbox:{{bbox}}];
(
way[leisure=park][!name][noname!=yes];
rel[leisure=park][!name][noname!=yes];
way[recreation_ground][!name][noname!=yes];
rel[recreation_ground][!name][noname!=yes];
);
out geom meta;


Please be friendly even if all edits of a user are junk. Add a changeset
comment to all reverted changeset to inform other mappers that they can
continue reviewing other changesets and comment one of the changesets of
the newbie telling him that edits have to match the reality on the
ground. You might include a link to
