She has explained, and based on what she says, I believe she was justified.
Reason: Every admin, in some way or another, has done something like this.
Whether it was killing another user, banning someone annoying, just being in a bad mood, using illegal items, being hostile in chat, we've all done something like it at some point.
With that in mind, Bjzrgood has been unbanned (and is now moderator, what ya know) lilacLily has been unmuted, and will have her stuff returned, and mio has agreed not to use illegal/op enchants so openly. We all slip, so no one is promising this won't happen again, or so publicly, but it will be easier to remember and prevent in the future.
