Actually, the BDG is not entirely made of bad googology. Sometimes the only reason that a number is listed there is because it lacked sources. For example, ggggol, gwtfol are perfectly well defined numbers, but they lacked sources and were deleted, and has been listed on the BDG because of the funny name.
