While this added a lot of Wikidata tags to places that had none so far, it also added at least a few false positives. node/244084738 for example has been placed in Yemen. Generally what I had been doing when determining whether a particular Wikidata item matches the place I wanted to add it to, was to at least also check things like matching province and country.

Apologies for the large area; RoofMapper's random jumping around along with combining everything into one changeset meant that after six roofs all was lost already and I decided to just continue as it couldn't get much worse anyway.

You're right; I was lazy with the changeset message here. Not mapping them as areas was intentional here, though, coming from the following section in the Wiki: osm.wiki/Tag%3Asport%3Dbasketball#Court_without_markings (the Maproulette task has been marked "Not an issue", accordingly). But now that I look at it again, they could probably be an area as well, just not rectangular.

Kann man an der Bushaltestelle eigentlich irgendwie kenntlich machen, wann diese benutzt wird (es gibt ja drei Haltestellen gleichen Namens)? Ich glaube, diese ist nur abends bzw. am Wochenende in Benutzung (da nimmt der Bus 18 glaube ich eine andere Route, die bei Hirschau Kirchplatz umdreht, statt bis Oberndorf zu fahren). Oder geht sowas zu weit für OSM?
