The bulk update request #1922 is pending approval.

create alias black-tie (1) -> mortis_kull (4)

Reason: Same artist, on old FA user page archives they say the "I'm mostly active on mortis kull: https://web.archive.org/web/20150330174050/http://www.furaffinity.net/user/black-tie/
...do we need to make it black-tie_(artist)? Only 1 user ever mistagged it: https://e621.net/post_versions?commit=Search&search%5Btags_added%5D=black-tie

Regarding the hyphen thing, there are around 203 posts with black_tie. As I have arbitrarily decided my threshold for alias false positives is 1%, and 1/200 is less than 1%, +1.
