Re: 'I have never chosen to share'
I was forced at work to create a facebook at work account, we used sharepoint for internal stuff (internal sharepoint) then was the migration of our parent company to the 'cloud' office 365, out sourcing the internal infrastructure and then facebook at work. I didn't follow the email that was sent out to go in to facebook and fill in my details for months, then i started to get emails from specifically to me from higher up saying sign up is mandatory. So had to go and do it, filled in the minimal details, disabled all notifications etc and have not done anything since with the account.
