Should you nevertheless persist you have no one but your own sorry ass to blame. You have been cautioned.
In case someone didn't quite catch my drift here: The point isn't that I'm going to be mean to you if you sell or buy things. I honestly don't care that much. The point is that if you get scammed, or robbed or have goods handed over to you only to then be killed and have them stolen right back as a legitimate game move, I'm not going to help you and nor, I would wager, will anyone else.
