Kind of scary. So I went looking for a solution. And there is one, but it is buried deeper in the security settings. Check out this article:
Now get out there and fix it.
So here's the deal. Almost anyone can look you up via phone number in facebook. I took my number OUT. I don't care if I cannot update or whatever from the phone. Almost ready to deactivate my account.
ETA: Turns out 'Jenn' is some sort of webcam girl. Sure she is. She "thinks she lives close to me. If I was up for something fun tonight" Sent me a link to her page. "keeps her safe, minors out, blah, blah, yada yada."
Yeah, I don't give a rat's ass. Forget my flippin' number okay? Shit weird-ed me OUT.
