Facebook should give us the option to prevent people from adding us to groups without our permission! Our profiles are seen by potential employers and clients, and someone might add us to a group we do not support without our knowledge or agreement.
Why is this important?
Because I have over 3,500 Facebook friends, I am often added to several groups a day. It takes time that I could be using in other ways to remove myself. A couple of the groups have endorsed beliefs that I do not share or endorse. I want the freedom to choose which groups I join.
