Facebook group admin protocols are seriously screwed up

I was admining a group for the original creator who is offline for a while. I gut busy myself, so decided to add another admin to take over. There were other admins but no one who monitored the site day to day and okayed new join request. The guy I chose (added by one of the other admins) turned out to be a real ass. He removed all other admin including the creator of the group and myself, which I had no idea was even possible. Why would facebook even allow such a thing? That's just really stupid. It basically means that you can never have another admin of your group because you'd always be worried that someone might get mad at you or be a troll and just remove you from your own group. I will certainly avoid creating one all together if this is the standard of group security. Any one else encounter this problem?
