Thank you

How do I email the site owner?

A VrChat user came into the world I was in and ripped my avatar without permission and posted it on ripper store. I technically didn’t even make this avatar because my friend actually made it for me and he would be devastated to know that it got ripped, and he’s a beginner in this avatar business. So please, please help me get this avatar taken down, this avatar is like my pride and joy and it hurts to see this happen too it. The thumbnail is a picture of the avatar in question.
