I am not on Facebook and still get invitations from Facebook members I do not know. I’ve tried filtering Facebook emails (in From, Subject, Body of email) and they still come through. How can I get rid of this annoyance?
This user is not in Facebook and he does not want to receive any invitation from Facebook. When some one is inviting you to join Facebook, the invitation email would look as shown below
If you do not want to join and also not receive any future invitation from Facebook then you can click on the unsubscribe link available at the bottom of email. This would display the following window asking for your confirmation whether you want stop receiving email from people through Facebook.
On clicking the Confirm button, the following success message would be displayed that you have opted out of Facebook emails.
