Thank you for your private message and for confirming that the deletions were intentional.

However, the fact that a path or way is not public does not necessarily justify its deletion. In OpenStreetMap, we use access tags to indicate whether a road or path is private.

Could you please undo your changes, or would you like assistance with this?

Ideally, an access=private tag should be added to the paths.
