The bulk update request #8746 is pending approval.
remove alias big_top_small_bottom (0) -> big_dom_small_sub (42028)
Reason: Followup:
alias big_top_small_bottom -> smaller_penetrated alias small_top_big_bottom -> larger_penetrated
top/bottom are not the same thing as dom/sub, I suspect this alias has led to many mistags. larger penetrated and smaller penetrated are more established tags that use less ambiguous language.
