As you seem to know your way around OSM as you state in your other comments, you know already that not all maps display the full data from the OSM db. This leads to the users of for example StreetComplete can't see certain playground tags on the map and think it isn't in there. Users with bad eye-sight in strong sunlight might not be able to use all map applications to see if something is correct or not. To encourage users to help with updating the map it's good to keep a nice tone and to scare away people that is trying to help by using their time to send notes. If it's already there, just close the note, no need for sarcasm. Thankyou.
