The bulk update request #11391 is pending approval.
create alias snout_fuck (1485) -> snout_penetration (0) # has blocking transitive relationships, cannot be applied through bur
create alias beak_fuck (63) -> beak_penetration (15) # has blocking transitive relationships, cannot be applied through bur
create implication snout_fuck (1485) -> penetration (921369)
Reason: Beak_fuck implicates Beak_sex. According to the wiki, the difference is beak_fuck is a penetration tag (specifically for penetration involving a beak) while beak_sex is any sex involving a beak. Same with snout_fuck (penetration with a snout), which beak_fuck also implicates.
The tags beak_fuck and beak_sex don't make this relationship clear at all. Without reading the wiki, one might even assume "beak_sex" and "beak_fuck" would imply the same thing, which is probably why a lot of people haven't used beak_fuck (it currently stands at 63 posts). In comparison, beak_penetration and snout_penetration is clear from a glance and is how every other '<body_part>_penetration' works, which is likely what people are used to.
Snout_fuck should also imply penetration if it's for snout penetration and sex is already implied to it. All posts I can find in snout_fuck -penetration still include penetration, it just wasn't tagged.
