The current OSM Notes dump and the OSM API contain "hidden" Notes

[pa5cal]

When I download the latest OSM Notes dump, it contains OSM Notes that are no longer visible.

How can you reproduce it:

1. wget -q -N http://planet.openstreetmap.org/notes/planet-notes-latest.osn.bz2
2. bzgrep '3939153' planet-notes-latest.osn.bz2
3. https://www.openstreetmap.org/note/3939153

On the other hand, the API still returns a result as json. Something seems to have gone wrong here when "hiding" the note.

That will just be openstreetmap/openstreetmap-website#2146.

I think this is not correct. At least for me it's the first time that the OSM notes dump contains a hidden note.
Please correct me if this should be the case.

Edit: Ok, some other already reported this, see openstreetmap/openstreetmap-website#2146 (comment)

IMHO, the OSM notes dumb should not contain hidden notes, that's nonsense.

Well there is no such thing as a hidden note - notes themselves can't be hidden but comments on a note can. You can see that in the API response which is a bare bones response with no comments as all the comments (probably only one in fact ) are hidden.

That's essentially the source of the whole problem, that things which should be part of the note instead have to be guessed from the comments.

I have no idea what the notes dump does but I imagine it does much the same as the API and skips the hidden comments leaving a bare bones container for the note.

Apparently notes can be hidden, but that one hasn't been, and neither has the comment. Rather what has happened is the author of the comment has deleted their account which is exactly the bug that I pointed you at.
