I Googled My Cell Number

I just out of curiosity "googled" my phone number. I was very surprised that a link popped up for "Airforums" showing my private email conversation where I listed my phone number for another members information. I conclude the message section is not closed or private. I'll be alert to this in the future. Going thru my PM 's deleting items, which is probably too late since Google caches all these goodies. We have had a rash of mystery phone calls, of which, five documented numbers I gave to our cell carrier to block.
