Guild Leader is Banned or Inactive
If your Guild Leader is inactive for at least 21 Days, the highest ranking active members are able to demote the Guild Leader and promote themselves to Leader.
There can only be one Guild Leader per Guild. The original Guild Leader must be demoted before someone can promote themselves to be the new Leader. Generally, a player of a higher rank than you must be inactive to be removed from the Guild.
Removing an inactive Guild Leader
To demote, promote or kick someone from the Guild, select the inactive player's name. On the menu that appears, select the action you'd like to take.

Guild Leader is banned
If your Guild master or leader is banned and you need someone else to take over, you can contact support here and request that the next highest rank be promoted. We will only consider promoting someone within the 21 day inactivity period, if we can confirm they will not be unbanned and we will only promote the second in rank.
Should there be multiple in that ranking, we will promote whichever player has been in the Guild the longest.
