I hate the fact that people trash bothies, but the information about their locations is public and has been for a long time (each MBA bothy has its own map on the MBA website, for example). Social media is probably more to blame for people trashing them than them being mapped on OSM.

If you’re trying to stop bothies being trashed by removing them from one map, that’s not going to work. That horse has bolted years ago and the stable door is broken.
