For example, I can’t find any “nobody” option that does this:
This section has other important privacy tools you can fiddle with, including who can look you up with your email address or phone number. We’d recommend … no one.
Lastly, for some fun insight into how advertisers think of you, click on Your Interests. There you’ll find all the categories Facebook uses to tailor ads for you.
More accurately, it says “Your information” (on the Ads page). (EDIT again: Nope, it has both.) They already know this stuff (well, the stuff they got right, anyway), and they’re going to hoover up even more; all this does is not show me ads based upon it.
I’m just that much closer to closing my account. It’s the only means of contact I have for old friends/acquaintances, but in all honesty, it’s not like I was staying in touch before FB, and I’ve (deliberately) been on less and less over the past month.
