That's one incident. I'm talking about a pattern of behavior where staff members act unprofessionally. That includes telling your users "I can just change your ID lol" even if they don't end up doing it.
Discord didn't fire the person who was joking about database edits the most (or anyone to my knowledge). All they did was close the outlet for staff to show their badge off and brag about it. That doesn't fix anything, my assumption is that this is still going in.
