I noted that some pictures of bats are also tagged as vampire and therefore, get an undead tag automatically. I am not quite sure what would be the best way to get around that. I started removing the undead tag and changing vampire to vampire_bat (if they show them with long teeth, drinking blood etc.) and removing it altogether otherwise. If they show any of the Dracula cliches (except drinking blood), like not appearing in a mirror or look a bit dead, I leave the vampire (and undead) tag. But maybe it would be better to have vampire_(myth) and vampire_(animal) or to remove the implication?
