The bulk update request #11565 is pending approval.
mass update multi_penetration -> penetrating_with_multiple
Reason: These tag names are confusing. There is no reason that tags with names this similar should have significantly different meanings. multi_penetration seems designed for characters with multiple penises or tentacles putting them to use on one or more characters, rather than one recipient being penetrated by multiple, so there is a place for it for searchability, but it desperately needs a rename.
This is a two-part BUR to move multi_penetration over to penetrating_with_multiple. I considered penetrating_with_multiple_appendages since the current wiki specifies non-object penetrations are excluded (only for multi_penetration, but not for multiple_penetration?), although that's quite a bit longer to type and would be awkward as a root tag if subtags were created (subtags generally add prefixes and suffixes, not replace them, eg. appending _penises to get penetrating_with_multiple_penises).
These are pending in a follow-up BUR to ensure that there's no order-of-operation issues:
alias penetrating_with_multi -> penetrating_with_multiple alias multi_penetration -> multiple_penetration
This isn't set in stone. If you can think of a better name, please let me know. The tag can also be renamed later with not too much headache.
