It's the opposite of what was talked about above. They aren't using Craigslist to figure out when people won't be home, they are using it to lure people to a particular place to rob them (and make sure that they will have cash on them).
Craigslist has had its share of issues with people getting robbed. I don't necessarily think that Craigslist is a bad thing though.
You have the same issue with valets. You give them your keys (which probably contain the keys to your house/apartment), your insurance information is in the glove compartment (which contains your address), and they know that you're not at home because you still need to get your car out of valet.
