When one tries to become more independent of Facebook, it can lead to some surprising results, and I have had to deal with one that has me effaced.
My friends who were a part of my account keep getting invitations to be friends. After trying to rectify the problem, if you are still getting notices, and this goes for any other person having the same problem; unfriend the person
who has been seemingly sending such notices repeatedly.
It is only mechanical. It eliminates the account successfully, and the person who has unsubscribed does not know.
