Does the Message Provoke?
Whether it's a Facebook post or a direct message via Twitter, McLean suggests you pay careful attention to the structure of the message: If the message is provoking an emotional response, don't click.
"If its saying something like, 'Hey is this really a picture of you?' or 'See who has unfriended you!' that's what you should zero-in on," McLean says. "And always be wary if they're offering something for free."
