The Discord subreddit has a few threads about this, but it has always been an open secret back when the Discord Developers guild still existed. I'm pretty sure it got axed because some staff members got too memey about abusing their database access.
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.
Could you please provide some sources? As the other poster noted this is the first time we hear of this. Would be keen on knowing more
