As far as other members of the guild know the gm has jusst stopped playing.. the GM's are not allowed to name people that have been banned
So Yes the guild will go on as it had in the past
This it was added sometime in cata I believe. After about 30days of inactivity the guild officers will be offered by the game to take control of the guild or they will have the option to become guild master.After a timeframe, you will be able to select an option to take control of the guild if you are the next in line rank wise.
