FB is known to build profiles of pretty much everyone it encounters, even vicariously, ostensibly to be able to populate a new account with engaging info once they actually join. Can I tell them to delete the records of my face that they keep even though I don't have an account? And, of course, in all instances. will they actually expunge it from all locations in their data-universe?
