I made a mistake

Hey, I need some help from the mods. I accidentally posted something to the Gitea discord community that was meant for a different discord community. It was a video. Well anyway, my account was banned and I am not able to give an explanation that it was an accident as I didn’t realize that I was posting it to the Gitea community. I wanted to try and dm a mod here, but I am unable to figure out how to do so.
