Yes, it is a fascinating topic: Fictitious or fake entries are deliberately incorrect entries in reference works such as dictionaries, encyclopedias (including Wikipedia), maps, and directories. There are more specific terms for particular kinds of fictitious entry, such as Mountweazel, trap street, paper town, phantom settlement, and nihilartikel. https://en.wikipedia.org/wiki/Fictitious_entry https://en.wikipedia.org/wiki/Fictitious_entry In cartography, a trap street is a fictitious entry in the form of a misrepresented street on a map, often outside the area the map nominally covers, for the purpose of "trapping" potential plagiarists of the map who, if caught, would be unable to explain the inclusion of the "trap street" on their map as innocent. On maps that are not of streets, other "trap" features (such as nonexistent towns, or mountains with the wrong elevations) may be inserted or altered for the same purpose. https://en.wikipedia.org/wiki/Trap_street https://en.wikipedia.org/wiki/Trap_street
