Possible tagging mistakes

Do not use this tag for land form (natural) basins e.g. the Amazon Basin. There are no tags (yet, 2018) in OSM for mapping such features.

If you know places with this tag, verify if it could be tagged with another tag.
Automated edits are strongly discouraged unless you really know what you are doing!
