The Sims 4 has a double standard - allow #transfem on the gallery!

Today I was making a townie to upload to the Sims 4 Gallery. This Sim was meant to be interpreted as a trans woman. The tag #transwoman works fine. The tag #transfem appears to be banned, with me receiving a popup that "The content contains a disallowed word. Please edit to resolve the problem." Once I removed that tag, the upload could continue as normal. What's more is that the tag #transmasc is allowed and DOES upload to the gallery, meaning the Sims team is specifically targeting the transfem tag while leaving its masculine counterpart. Why is this? What leads them to allow trans woman and transmasc (among many other trans- tags), but transfem is too inappropriate?
