Hi,
My admin friend, has said for ten years, that the spoof'ing in those places is out of line and there is no security by the company at all.
I have, always, refused to enter into any of these ... I never thought myself as "paranoid", but I simply don't like the shoot to kill and don't give a damn, type of attitude in some of those places, even with "friends", who for some reason, always come up with a post that belongs to some weird Fred out there that is a bad copy of the original Fred who is OK in my book!
I feel safer here, than I do in Facebook!
