Hello, Welcome to OSM. Looks like you have a new account, so I'll give you some info on the OSM project. If a feature actually exists on the ground should not be removed from OSM, regardless if it's private or public, designated or informal/illegal/unauthorized. Please don't remove valid data from OpenStreetMap.

The correct way to handle this is to use the tagging system. access=private seems to apply here. Once this is done, services that do use OSM data will reflect that and specify their access.

I've restored the feature, please use the tagging system if you think it's appropriate in this case.
