In accordance with Wikia's official procedure for handling it, I've started a public discussion anyone can join on the Zero Escape Wikia regarding AlexShepherd's performance as an administrator there.
http://zeroescape.wikia.com/wiki/Thread:16338
Per Wikia's rules, if he removes the thread or blocks me for starting it, he will be the one in trouble with staff. However, the rules of such a discussion must be observed: don't use it to attack him. The thread exists to state facts and issues with him or the Wikia.
There were people in this thread talking about how they love Zero Escape and avoid the Wikia because of him, so this is your chance to list all of the issues there and maybe get something done about it. If he refuses, the discussion can be sent to Wikia staff to have his admin position removed.
Additionally, as the admin of a Wikia, he has to remain civil in handling this.
So please do contribute to the discussion.
EDIT: It seems his first act against the thread was to disable anonymous editing across the entire Wikia, without consulting the other active administrator. If he does anything else that seems motivated by preventing people from contributing to the thread without putting targets on their backs, I'm sending it to Wikia staff without delay.
