The bulk update request #10835 is pending approval.

create alias bondage_harness (155) -> harness (30120)
create alias tied_to_penis (60) -> bound_to_penis (4)
create alias bound_to_character (5) -> bound_together (2221)
create alias tied_to_character (6) -> bound_together (2221)
create alias tied_to_object (3) -> bound_to_object (55)
create alias tied_to_wall (24) -> bound_to_wall (40)
create alias tied_to_foot (143) -> bound_to_foot (3)

Reason: Not sure which tag is more universally used between "bound" or "tied", but there are a couple duplicates spread across both. Went with "bound" as it seems more generic.
