When you are admin of a Facebook group, you have to approve each member that wants to enter the group. In addition, you are notified every time someone asks for approval. If you are admin of a large group, this can cause a significant amount of useless notifications, but I can't seem to find a way to disable them. They don't appear in the "all notifications" panel, and the notification menu doesn't seem to be listing specific notification types anymore. Setting the "notification for this group" to "off" doesn't help either.
Is there a way to disable the notifications that appear when someone want to join a closed Facebook group where you have admin rights?
From Facebook's point of view, this is a feature, not a bug. FB wants group admins to deal with members ASAP. Your main options are:
(edit: open groups have the same approval issues as closed ones)
