There's an oke who I caught trying to change random listings in a small township in South Africa into something related to him. One small edit that was allowed was for him to map an existing road, but he named the street after himself. Map Maker has its flaws, many of them (like bots that go around changing information for whomsoever knows reason, the heavy-handed moderation in itself) but the moderation is sometimes necessary. We (or whoever is contributing and editing) also have to use common sense when making and approving edits. For me "documentation" could have meant going outside and taking a geotagged photo with a time stamp, if the moderator still wants more then to hell be with it.

Most of the edits that I have made have been for areas where I'm interested in walking paths, because I use the Maps API quite a lot, but going out of my way to map a city or something, I'd rather do that on OSM where it's free for all.
