I stumbled across this and though I would share. It seems like a really well thought out article, and is a really good read about how to deal with suspicious people. I would really like to get a discussion on this going, and if anyone has anymore material on this subject, please share.
Fair warning, this article discusses how to use profanity in managing contacts, and so it swears twice. If this is a problem mods, please just delete this topic.
