Hogyan tudom be állítani hogy ne vegyenek be semmilyen csoportokba facebookon?

Sajnos nem lehet :'(

Facebook súgója írja;

"There's no way to prevent one of your Facebook friends from adding you to a group, but you have a few options to prevent it from happening a second time: Tell the friend directly that you don't want to be added to groups without your permission. Block the friend. Unfriend the friend"
