I actually saw someone raving on about that in some comments-thread on derpibooru. Didn't bother to read too much of the discussion, but at a glance, apparently people were repeatedly changing the character's tags to whichever name they liked best until an admit set it up so that all three names automatically implied the other two to show up on search. At least I think that's what happened from a brief gloss over some of the comments.I don't know where the name came from, but if I had to guess, there's probably an anime character with the same hair-style.
