- male/male solo is an often made mistake when tagging. My assumption: Users try to tag a characters' sexuality even though: yaoi, fag, gay, homosexual, and homo, are all aliased to male/male.
- The same fore female/female solo and bisexual solo, but it's not that escalated, yet.
- For male/female solo it seems like, the misunderstanding that disembodied_penises count as characters, causes the false tags. I would still add hetero, straight, heterosexual to the BUR.
- For intersex/intersex /female /male solo there are no tag aliases, that could indicate sexualities.
I would suggest creating an unalias BUR:
unalias yaoi -> male/male
unalias fag -> male/male
unalias gay -> male/male
unalias homosexual -> male/male
unalias homo -> male/male
unalias yuri -> female/female
unalias lesbians -> female/female
unalias lesbian -> female/female
unalias bi -> bisexual
unalias hetero -> male/female
unalias straight -> male/female
unalias heterosexual -> male/female
And then a category BUR:
category yaoi -> invalid
category fag -> invalid
category gay -> invalid
category homosexual -> invalid
category homo -> invalid
category yuri -> invalid
category lesbians -> invalid
category lesbian -> invalid
category bi -> invalid
category hetero -> invalid
category straight -> invalid
category heterosexual -> invalid
