And finally redid what I actually wanted to do: osm.org/changeset/73312054

The mentioned tag problem stems from a problem with a superfluous node I selected before replacing the geometry. I reverted the changeset: osm.org/changeset/73312013

Thanks for welcoming me, but I'm here since 2007 :)

Sure!
This is definitely a limitation of maps.me and not having Web Access for GoMap!! to add the proper tags.

That was for sure not my intention, my fat fingers must have botched something on my mobile.
I’ll also look into it once my vacations are over and I’m back on a computer.
Thanks for fixing it in the meantime!

Thanks for the fix!

It has been known that 'Pokemon Go' players edit the map to influence the game: https://www.reddit.com/r/openstreetmap/comments/5q4ctl/warning_players_of_pok%C3%A9mon_go_may_be_editing_osm/

I thought this might be the case here, since several of your recent edits are parks where there is no park visible in the aerial imagery.
What is the reason to add a park outline here?

Ich hab' mir die Freiheit rausgenommen, das zu korrigieren: osm.org/changeset/71557478

osm.org/way/699356889 definitely doesn't look like a park on the aerial imagery, more like a parking lot or some industrial area. Can you give a source for it being a park?

This doesn't really look like a park on the aerial imagery. Do you try to spawn some Pokemons here?

Hallo
Da 'review requested': Der Recycling-Container (amenity=recycling) muss/sollte nicht die Details im Namen tragen.
Dass dort Kleider, Altglas und Alu entsorgt werden können, kann über den 'recycling'-Tag markiert werden: osm.wiki/Tag:amenity%3Drecycling

Danke!

Danke!

No, I didn’t check all the bad POIs, but I also stopped doing anything in that region after stumbling over more and more of those seemingly random POIs. Feel free to revert my changeset too, since I’m without JOSM for the next 10 days or so.

But I wanted to ask about the amenity=school and leisure=playground tag. As far as I understand it, this goes against osm.wiki/One_feature,_one_OSM_element and should be mapped separately.

I corrected the typo in "operator:decription".

Or http://osm.janmichel.eu/taginfo/newkeys.htm as I wrote above :)

Taginfo showed just this one instance.

Thanks for adding points of interest to OpenStreetMap.
You've added these points with a lot of 'marker-*' tags.
There is no way to override the display on OSM with these tags, so I removed them.

I removed the icon (and came from http://osm.janmichel.eu/taginfo/newkeys.htm)
