The bulk update request #5755 is pending approval.
create implication full_nelson_position (311) -> full_nelson (6122)
create implication full_nelson_position (311) -> from_behind_position (147830)
create implication full_nelson_(legs_held) (1180) -> full_nelson (6122)
create implication full_nelson_(arms_held) (68) -> full_nelson (6122)
remove alias full_vaginal_nelson (0) -> full_nelson (6122)
remove alias full_anal_nelson (0) -> full_nelson (6122)
Reason: The full_nelson wiki directly lists these three tags, and none of them can happen without a full nelson pictured. full_nelson_position is a sex position which also requires penetration from behind, so from_behind_position should also be implied.
