Hi there! The comment that you are referring to is from 2021, asked during our first year of the exchange. It was something we hadn't considered when creating the exchange and since the nominations were already closed, we said no. The rules have since changed to allow genderqueer characters and that includes nonbinary characters on the basis that it is someone that you would feel comfortable nominating in what is still a femslash exchange. I'm trusting people to use their judgment on this one. If you have any further questions, please feel free to ask.
