The bulk update request #12089 is pending approval.
create alias stick_figure_(species) (0) -> stick_figure (646)
create alias matchman (0) -> stick_figure (646)
Reason: A simple stickfigure is not a species in of itself, just a supplementary tag to add to a character [Or the main stick_figure tag can be changed to a species tag, or we can make an ambient_stick_figure tag, idk]. Matchman was being used for glorified stickfigure (circlehead) posts, but it is also a term to refer to stickfigures in general, especially the animated kind in China [火柴人], so it's best to redirect that alias to the more common usage of the word.
Edit, for clarification: matchman is considered more of a botched translation of 火柴人, and the accurate translation should be along the lines of stick_figure, according to the comments of post #4070300.
