Wrong, malformed and duplicate data at Menorca, Spain

Hello everybody!

Recently I discovered this (https://www.openstreetmap.org/changeset/53473705) changeset by a relatively new user (https://www.openstreetmap.org/user/Santi%20Benejam)
The user added about 2600 hotels and apartments in the area of Menorca, Spain.
The problem with this changeset is that he

  1. added all names of the hotels/apartments in upper case → results in a huge mass of osmose bugs and is hard to read
  2. added some inexisting hotels/apartments (e.g. in the ocean)
  3. didn’t take care of already existing hotels/apartments → huge amounts of duplicate data

In my opinion this changeset should be fully reverted, because this changeset doesn’t help anybody :slight_smile:
The problem is that he didn’t just added those wrong nodes but also modified them about one month later with this changeset: https://www.openstreetmap.org/changeset/53844401 just for adding note=Hotels, villas i apartaments. Zones recollida bus discrecional

I have no idea how one can fully revert those two changesets… Does anybody of you know how?
