why?

  I join all sorts of groups on fb, some of them private, and the ones that are private, they do a mini interview. There's a few questions and you have to click agree to the rules. Of course, how could they not have rules, the janitor's syndrome, it's not for nothing that they made their grouppy, they have to set up their own. The rules of all these groups are the same and converge with the policy of the resource. You know, like, be polite. 

Well, and here, there is a rule, and sometimes it is not in the list of rules, but you have to write with your hands the answer - yes.

So there's a rule: you can't ban admins.

...there's some the coolest story behind that rule, right? 

I want to know! 

What's it like? You come to the group, and you think, "This douche is annoying," and you ban the admin? And you continue to sit in the group? Well, that's how the admin has to bother a user to ban him? Why a user does not leave the group, if the administrator pisses him off? Well, we diccussed it with my family, what for it can be: you ban the admin, put a crap in the group, and admin does not see. But you're gonna get complaints from other users. It's like, if you break a rule, you'll be thrown out. That is, there are moderators, they will say, this man is crazy, users complain about him, admin will say: I do not see, he banned me. Moderator: okay, I'll throw him out. 

And so? What is any profit to ban admin? 0_0 

It's weird. A weird action. And a weird rule. Any person who wants to put a crap into the group will say: I will not ban admins and still will do that! How this rule can help?! 

So many questions...
