By now you've seen someone post about the 10 concerts they've been to on Facebook. The idea is that one isn't true and the person's Facebook friends need to guess which one is the lie. Identity theft experts are warning people to think twice before playing along. 

These types of posts are gold to scammers because they offer real information that can be used to hack people's accounts and ultimately steal their identity. "What was the first concert you ever attended?" or some variation of concert question is often used as a security question on sites that require passwords. People almost always share the first concert they attended when playing along with "10 concerts" post on Facebook.
