The tag alias #74757 ambient_crewmate_(among_us) -> ambient_among_us is pending approval.

Reason: These tags are synonymous. Both of their wiki pages are just slight rephrasings of "when an image has an Among Us crewmate in it".
Currently, ambient_crewmate_(among_us) implicates ambient_among_us, but I see no situation where an image could possibly be tagged with only ambient_among_us and not ambient_crewmate_(among_us) based on their definitions. One of these tags should be aliased to the other. Given ambient_among_us is the more commonly used of the two at the moment (due to it being the one implicated by the other), that's the one I'm suggesting.

The tags are not 1:1, an implication is fine.

As I've previously stated, there are going to be images where the ambient character has obvious monster/impostor features.
We do have a more detailed BUR (including a missing Among Us implication!) that has been sitting untouched for a couple of years, so I'm making sure to get it some admin attention soon.
