Leaving someone to learn from their own naivity is far better than taking items off of someone else ( i.e Gawin in this case ) who traded fairly just to make it all better for the guy who was stupid enough to get scammed in the first place. Hope Gawin gets atleast his starting items back and whoever got scammed learns from their mistake.
Trusting strangers, especially over the internet, is a very stupid thing to do, atleast where I come from, I am surprised this is still happening to people after all the scams the other week.
