Do we really need a karma_sutra tag?

I recently found this tag by random chance, and it describes itself as a "common misspelling of kama_sutra". At the time, it had exactly two images, and I removed it from one of them (replacing it with the correct tag). But the second image, post #170291, is where the ambiguity happens, because the book is actually misspelled in the image.

Personally, I think we shouldn't have this tag, because if we allow misspelled tags, then that would set a precedent that every somewhat common typo gets its own tag. typo is invalid, which is precisely why I'm asking this question. Wouldn't it make more sense to use something like kama_sutra misspelled than karma_sutra? If it really is a common typo, then maybe the tag should be aliased as well.

Nope, just throw a note over it correcting it.
