otona_no_kitsune (0) - old and unused
konza (0) - The current name is used on pixiv, but it is unused here.
konzaburou (449) - The current name is used on booth.pm, and popular here.

Reason: Artist with a triplicated tag

That's not how we alias tags. You'll need a BUR.

The bulk update request #10491 is active.

create alias otona_no_kitsune (0) -> konzaburou (455)
create alias konza (0) -> konzaburou (455)

Reason: I have no idea where the artist (also once known as Kzr) used Otona no Kitsune, but their Wikifur article mentions it, if that's good enough. :\

On the other hand, they use Konza quite a bit, on their Pixiv, their Inkbunny (which it seems https://inkbunny.net/konzaburou redirects to), and their Pixiv-linked Misskey.io (which if you scroll down, links to their Konzaburou Booth.pm.
