It was inevitable that the criminal mind would try to exploit online classified-advertising forums such as Craigslist. Criminals are active in the real word, and the virtual world is just an extension of the real one.
However, I suppose the lack of real privacy online works in society’s favor when it comes to criminal activity. When you are on Craigslist or Facebook, you are traceable. You leave electronic tracks behind.
On Facebook, the proprietors can use those tracks and your user data to exploit you as a consumer entity in their dealings with advertisers. That’s the dark side of being an online denizen of an electronic social network.
The bright side is that criminals who use Craigslist typically will be identified, apprehended, prosecuted, and imprisoned. They are highly unlikely to get away with their crimes.
