It's one of the reasons I see networks I've detected, suddenly appearing in places I never stumbled. Someone else detects a network, which has the same BSSID during AdHoc operation, that the network detected by me had, and during the next update of the Wigle Map, it has suddenly been teleported from Denmark, to Ohio or Australia..
