Agree with most of what you say, just the name "trolltag" implies that someone was doing this in order to disrupt when often no negative intention is involved. > In many cases (like this two cases above) correct mapping is no mapping > whatsoever. Yes, with one exception - if a building has been demolished but is still visible on the aerial imagery most commonly used in the area (usually this will be Bing), then - at least until we have a "meta database" that contains information important for the mapping process - it may make sense to leave *something* there (perhaps a way tagged only with "note=the building you see on bing was demolished") in order to ensure that the building isn't re-created again and again by armchair mappers.
