Hiya, when marking caravan sites as disused, simply deleting the name will not work. That leaves the site still tagged, but nameless.

Instead, you need to change the `name` tag to `old_name`, and `tourism=caravan_site` to `disused:tourism=caravan_site` as per the lifecycle prefix documentation (https://wiki.openstreetmap.org/wiki/Lifecycle_prefix).

I’ve done this for this changeset in https://www.openstreetmap.org/changeset/172631067, but I am not going to do it for all your changesets.

Happy editing :)
