Quite simply, setting up these things is a nightmare on this site. It's extremely hard to get it exactly the way you're wanting when you have to blindly edit it yourself then upload it again and again until it's right (not to mention data wasteful on a site with really small file size limits.)
Virtually all other sites I can think of these days have ways to configure the avatar. It's a basic feature any social media site should have.
if you wont do it for lay users please do it for the OCPD posters
