Hi, i have this friend but he is also some sort of my biz rival. I saw in his FB, he is also a part of some of the groups i am in. If i post in that group he will get a notification. How do i make it that he will not receive a notification and also unable to see my post in the group. Thanks
we could do an experiment tell us the group I'll join it you can block me then you post something benign and I'll let you know if I can see it and then you can unblock me I presume he isn't a "friend"
