It does suck that all avatars are kinda just out there, but that is the nature of VRChat. I have my personal avatar that I have spent so much time on, and I cannot ever use it because as soon as I go into a world with even ONE person in it, its out there. I never upload my personal works. It sucks, but if you want to keep something private right now, you have to keep it to you and you alone. ❤
