Another one I don't expect to be popular but maybe a few people will really like it.
(Ilust and Pony): If you don't want nuts then you might need to put "testicles" in the negative. The dataset had a lot of balls. Oh also "tail" so you might want to put that in the negatives too.
In summary:
Trigger word(Anima): double anus
Trigger word(pony): double_anus
Trigger word(Illust): twin_exhaust
Helpful negatives(IL + Pony): tail, testicles
FYI This dataset contains zero men so if it works for men, great but I have not and will not test for it.
Side note: I do take informal requests(basically a bounty that you don't have to pony up buzz for) if I like the idea(Tips are nice but not required since if it's a good idea then I'll get generation Buzz). Just leave a comment on one of my models or DM me. (Comments are preferred since that let's other people see that I'm actually fulfilling informal requests.) DMs are perfectly acceptable if your request is a bit out there and needs some image examples or something.
