Sure, and I’d probably understand it from the instance owners perspective better if I were in their shoes. And to be fair to them, my username was randomly generated by youtube at some point. So if they just outright reject appeals from generated usernames, I definitely fall into that category. I just feel like that’s a bad process and practice for instances which are among the top of the suggested list for new users.
Considering that some bots might also have automatic appeals integrated makes it more reasonable to expect that automated rejection.
