I posted a picture in a Facebook group that I’m a member of. A friend of mine who is against the ideals of the group left a snide comment on it.
So my question is, is there any way for your Facebook friends not to see pictures that you post in groups that they’re not a member of?
You are presumably posting in an open group. If the group is closed or secret then non members won’t see what is posted.
Your best bet is to delete the pic and send him a polite note to leave your postings in this group alone. If he refuses de-friend him. The group can go closed but that sort of defeats the purpose of group trying to attract members.
