AI image generators broadly cannot handle negative prompting. I learned this when I was trying to generate a mini figure that looked like my sister with her guidance. 

The AI really wanted to make her scantily clad and I tried to fix it by saying "do not show cleavage" and similar but it can't hear negatives so it kept just showing more and more boob to my absolute frustration.

with midjourney for example you can use the option --no cleavage 
(but in general i agree, i think that's why there's this separate --no paremeter)
