Got approached by a local of Batong Malake (in Los Baños, Laguna), because I was mapping certain amenities and housenumbers. He was less than pleased (and he has a sticker on his car identifying himself as a member of a local gun club, as he was driving a car at that time) but I assured him that his privacy is guaranteed.
What's wrong with that? Simple: I was mapping that guy's housenumber.
Is there a clause somewhere in the OpenStreetMap wiki (or some blog managed by OSMers) stating that we can't describe the occupants of a certain housenumber (especially if the occupants are very paranoid when it comes to their privacy), except if it "houses" an actual amenity (like restaurants and convenience stores)? And do we need ID's to confirm our identities as volunteer surveyors, if we are suspected of doing something bad (like preparing for a robbery or a more dastardly and criminal act)?
