I would suggest you followup with a request to facebook for whatever information they have on you, once you feel you've completed your deletion.

As someone who has never had a facebook account, though just about 99% of the people I know do, I am interested to see what this "shadow profile" of me looks like.

My wife and others have logged into FB from my machine, phone and ipad previously - thus I am sure that there were periods of time where my actions were tracked based on the install of their cookies.

I'd wonder what the legal basis would be of FB tracking those without accounts, based on the cookies of others.
