A few days ago there was a lot of imports, including this changeset: https://www.openstreetmap.org/changeset/33551525
All using a lot of bad tags which was finally reverted by FTA_dwg.
There are just a lot of similar edits, mostly by new users with at the end only up to 5 edits.
They can be easily identified by overpass: http://overpass-turbo.eu/s/dZA
Used tags are: Keywords, Hours (Of Operation), Business Email Address, Category, Payment options, Year Established, …
(New tags to OSM are visible at http://osm.mueschelsoft.de/taginfo/newkeys.htm=))
Newest edit is:
http://www.openstreetmap.org/node/3965279362
Some users (including me) already tried to improve tagging and to contact them, without success.
How does the local community think about?
