It is perfectly possible to create an Overpass query that extracts paths at the time that Stef did his surveying. Then we can overlay it with the current situation. It is also possible to track all changes in this area. Or build a script that sends a warning when it seems some new paths were created or the access changed. And if it turns out a user is continuously making incorrect changes, we can talk to them and if needed block them. I can help set something like that up. But let's discuss this in the forum or via communit@osm.be, not here.
If specific things need to be fixed here, please create a note for specific things.
