Aliasing not_cub → invalid_tag
Link to alias

Reason:

It's easier to simply not tag cub than make a new tag. Probably born from worry of the sole image using this tag (post #1814168) being tagged as young. Besides, TWYS overrides if the character looks young enough.

sounds like more of a tag that was created because someone was salty that their image got tagged cub though their characters lore age isn't one. Either that or tags were transferred from inkbunny or something.
+1 get it out of here.

Edit: Ya, the tags were transferred from inkbunny

Approved!
