None of these tags are too widely used, so it may be better to simply fix all instances of them rather than make a BUR or make them invalid. Let me know what you guys think.
A couple examples of the tags I'm talking about:
partially_clothed_female_nude_male (114 posts)
nude_female_clothed_male (69 posts)
Or worse:
partially_clothed_anthro_nude_male (bizarrely, at 122 posts)
These tags should definitely not exist and should just be tagged as their individual parts. I'm a bit unfamiliar with the process - if a BUR was to be created here, would I be correct in assuming we would start with implying their individual parts, then making these tags invalid in a follow-up BUR?
Ex:
imply partially_clothed_female_nude_male -> partially_clothed_female
imply partially_clothed_female_nude_male -> nude_male
Then in another BUR:
alias partially_clothed_female_nude_male -> invalid_tag
