If an admin isn't making unauthorized changes then they are doing a great job and won't get called out on the forum. However if they are screwing things up by doing stuff they are not supposed to be doing then why is it wrong to say so publicly in the hopes that other admins get the message not to? It's not like the devs would make up the fact that they have had to spend a lot of time fixing things caused by some rogue admins. What would they have to gain from doing that?
We just had a highly respectable guild member mysteriously banned today from the server with the reason being "you know why", which he did not. I don't know if it was a mistake or abuse but something is wrong.
