over the past few years i have joined a lot of facebook groups: australian doulas, sydney doulas, postpartum doulas, a hippy mums group and one promoting a more inclusive church (just to name a few)
it's a funny old thing, the facebook group. some of them have almost no rules, some have long lists of rules. the "please be civilised and nice rule" is expressed in many ways but it's mission is always the same: to avoid offence. I see the point of it but sometimes i would love to see a rule saying something like "if you behave like an idiot in this group we wont kick you out or delete your posts, we'll leave your rudeness and stupidity right there so everyone gets to see who you really are" It would be way more informative than having the nice police everywhere.
a week or two back i joined a nanny group. I had to pass a rigorous approval process, becoming "friends" with the moderator so she could see all my facebook business, then being unfriended so i couldnt see all her facebook business. three days after approving me she private messaged me saying only "please adhere to the guidelines" It was a little disconcerting. i re-read the guidelines and didnt seem to have broken any, i even PM-ed back to ask if i had broken the rules. she never answered. i guess it was a pre-emptive strike. very weird.
it's just a theory of mine but i think you can tell a lot about a person by the way they run a facebook group.
