The bulk update request #10929 is pending approval.

create alias nakedsharks (1) -> pashoo (170)
create alias nakedsharks_(artist) (15) -> pashoo (170)
create alias naked-sharks (13) -> pashoo (170)

Reason: All three of these tags are redundant because they're just slight variations of the same one. But in addition to that, I think they could all be merged into pashoo, the artist's main alias, because there's no consistency to how they're all tagged on here and the distinction doesn't seem to matter too much. Only a handful of the posts are tagged solely as nakedsharks, the vast majority (even if they're explicit) are tagged only as pashoo, and a handful are tagged as both.
