  The app protects against this: if there is an open note at the exact coordinates where a quest would be shown, then the app will hide that quest (for all users). So any individual quest should never generate more than one note, unless the note gets resolved without changing the tagging and then someone else comes by and leaves a note again.
  
  Actually it's less than one note per quest, because multiple quests for the same OSM element would all appear at the same location & be "blocked" by the note.
  
  This is also a protection against entering bad data— if an element is confusing for one quest, there's a good chance it's confusing for a different type of quest that might apply to it (or mistagged).

  This is unfortunate. I think I remember reading that there is no way to attach metadata to OSM notes (e.g. to mark them as low priority), and so the next-best option (which is currently used) is to include the text "via StreetComplete v{{version}}" at the end of every note, so a different editor *could* filter them out, even if in practice that doesn't happen yet.
