Welcome to ECF.
And I trust everyone knows that, when you use Facebook to login to other sites, Facebook gets to track what you're doing. They know the members of your family, your friends, home address, political views, purchase and credit history, who you call and text, prescription drug history, route taken to and from work, where you
shop, foods that you buy, that you're a vapor, etc.
If you threw in emails and search history (e.g. google), these corporations know more than your own mother. Most have no idea how little privacy remains.
