If you've ever actually visited Craigslist you may be under the impression that there simply aren't any rules against what you can post. However, while that assumption is mostly correct, you cannot, for what we hope are obvious reasons, sell guns to complete strangers on a forum that has been known in the past to connect violent criminals with their victims. Luckily though, where there's an Internet rule, there's always an insane person trying to bend that rule in the most clever and/or idiotic way possible. Exhibit A: This "DVD" sale which is destined to become an actual Exhibt A at a murder trial.
