How do we deal with a hacked account?
We had a moderator get angry and leave /r/squaredcircle and delete their account.
They have now banned users and are deleting content with our flairbot's account - http://screencast.com/t/kqBSSEJ8vJkX

Can anyone assist?

Flairbot was a shared mod account?
It was a shared account with the mods and the flairbot - we used it to maintain a few general posts and to work around the limitations of the Reddit API requiring a password and an account with enough legit karma to not get the captcha when posting confirmation messages from our flairbot (http://sc.bonked.me/flairbot)
