Some time ago I got an invitation from one of my friends to join a facebook group. As usual I ignored this invitation and did nothing about it.
A few days later I got a messenger message from the friend on this group. And since then am getting messages from various members of the group.
I am not joined to this group and not following it either.
My question is; how is it possible that without being a member of this group I get messenger messages from the group?
I even cannot find a way to disconnect from the group either in messenger or on facebook.
I would like do do this on my own and not by asking the group admin a favour.
