Delete POI's

To delete a POI, first show them on the map (click the map filter on the top right corner of the map, then turn POIs on), then you can click on any of them and a delete confirmation appears.

If you play on PC or browser simply click on the POI again. The site will say: "Are You Sure You Want To Delete POI:POI NAME?" Then click yes. I dont have a solution for mobile though.
