The cover art upload form should display a clear warning that images might contain sensitive metadata that one wish not to publicise. Particularly location data seems undesirable for cover art since these are often taken at home and can pose a privacy problem to the uploader.

So far I've witnessed two cases of users who either learned about this after the fact or seem unaware of this:

• https://chatlogs.metabrainz.org/brainzbot/musicbrainz/msg/4615917/

  <chaban> Just spotted an editor who learned the hard way that a photo they've uploaded contained EXIF location data and due to MBS-4753 they can't easily undo this mistake.

• https://chatlogs.metabrainz.org/brainzbot/musicbrainz/msg/4645909/

  <chaban> Just stumbled upon another user uploading photos with GPS tags, presumably pointing to their home.
