I can't say, as I wasn't a part of the action. I'm at the hospital with my kid right now, but when I have time, I'll dig further
A rule of thumb: message the top mod (first person on the mod list) when you have a problem.
Everybody else defers to them, and we tend to not override them, as moderator powers trickle down - meaning if you look at the list, the person at the top can remove all those under them.
If you see a top mod abusing their power, go to the instance home page, and on the right, you can see the admins. They have god tier power, and can right wrongs mods can't.
