, if I was your brother, I would have a long, long talk with his daughter and there would be a loss of privileges.
About facebook, it is unfortunately: a sign of the times
Money walks, BS talks.
Personally my wife and I abhor social networking and neither of us would be caught dead on one.
Well, I did once, and that cured it for me. A few years back I wanted to try a program, but you had to join their facebook page to get it, what a mistake!
Emails and spam followed and when I had enough I finally found the unsubscribe button, that went better than I expected, but I started receiving spam telling me it was imperative that I check my security settings and it had a button designed to take me to the sign-in page. Yea, right!
That right there warns you there are bots scrubbing the site. It took a while but my filter won out, and if it starts up again I will know facebook still has my information and never deleted it. Fool me once, shame on you; fool me twice, shame on me.
