If so....what happens? I ignore myself, therefore I am?

Are you able to reverse the procedure on your own or is it like sucking yourself into a self-created Black Hole (TM)?
Can you Disallow Contact with yourself?

Okay, this is what I got:
"You have tried to add yourself to one of your contact lists. This is not allowed; please resubmit the changes without trying to add yourself to your own contact lists."
That's one more of life's mysteries solved.
