@plainoldme,
All the FB privacy settings are set up so that the maximum number of people can see your information and even use search engines to find you. You can limit that by going through the privacy settings line by line, but a lot of people don't do that. It takes two weeks to actually delete your account when it should take two seconds. The FB business model is based around getting you to share info so that vendors can target you and they go to extremes to hold that data once they have it. That said, I have used FB to get in touch with people I hadn't heard from in decades, so I see pros and cons. I just go through the privacy setting line by line.
