I posted an article recently regarding the recent illegal stuff that people utilize craigslist for. It's scary how effective it can be. People who are desperate will actually convince themselves that they can rob a person's house if there's an anonymous ad out there that tells them they can take it all. You can read about the
craigslist ad that got a man's house looted. Poor guy. If his neighbour didn't call him to come home from work, I wonder how much of the house would have remained?
