BUR #3223 has been approved by @evazion.
remove alias elf_ears -> elf
remove alias elven_ears -> elf
IMO elf ears should rather be aliased to pointy ears.
Pointy ears are just one characterization of elves, but i guess it´s an opening for mistagging, as some people rather tag 'elf ears' if they mean pointy ears. So some images, where no elf is depicted, will be tagged as elf because of this alias.
If this is approved, I will, in the next step, propose the alias from elf_ears to pointy_ears.
On the other hand, I would also propose to remove the implication from elf to pointy ears, as I don´t think that the implication is good. Missing ears from injuries or hair over ears could mean, that an possible elf will be tagged with pointy ears, even if you can´t see them. Or we have to remove every elf from posts, where you can´t see the ears.
Only topic I found: topic #8356
EDIT: The bulk update request #3223 (forum #170964) has been approved by @evazion.
