Welcome to OSM! I revert your changes set, because all nodes are moved more than 100 Meters

Welcome to OSM! Please don't add standard name to an object (like)
landuse = farmyard
name = Farmyard

Of course the key is not wrong, but you can see that there is only a short prefix before the ref. These are also in lower case. For quicker recognition of what the key can mean, the suggested variant under Extensions osm.wiki/Key:ref#Extensions makes more sense (if necessary also country code)

Welcome to OSM! You move a the node osm.org/node/3125170383 more than 100 meters. I revert your change set.

Please make sure that the changes are correct and not fun changes.

Welcome to OSM! Please be careful! You move the node osm.org/node/6817325093 more than 100 meter. Ich move the node back to the original position.
