I just downloaded and examined my Facebook archive data and other than some embarrassing old messages I sent to and received from friends through Facebook, they had nothing disturbing about me. This is coming from someone who didn’t take extra special care to protect myself, but also never consciously gave them information either. (They had absolutely no contact or phone info and I have used Facebook on my phone before.) If you use facebook like me you probably shouldn’t worry, but I’d urge you to download your archive.
