I think it is wise to have a closed group with approval. It keeps the sunglasses spammers and trolls at bay.
Even an open Facebook group is subject to administrator approval to join. Friends can invite new members without administrator approval whether the group is open or closed. However, an administrator can boot anyone at will. In the group I administrate I ignore many people daily as I can spot them to determine if they are real people or not. Every once in a while I get fooled and have to delete a message selling sunglasses, cheap watches or something. Also, a spammer doesn't get a second chance or warning.
Many forums have safeguards to keep fake people out. However, I am a member of some message board forums similar to RV.net that seemingly have an automated approval process because if I sign on in the wee hours of the morning I might see a dozen spam messages that some admin has to go in and delete almost on a daily basis. RV.net either has good safeguards or on top of it admins because I can't recall much if any spam here.
