A couple of minutes ago I was almost scammed. Luckily, I caught it in time. So, here is my proposal for an Anti-Scam block for trading. When you start the trade, you can specify what you want in a little box, and if the other person does not specify to those requirements, they cannot trade. This will not apply to COINS, only blocks. But you can specify how much you want in gold, so when the other person goes above or below, it will either change it to be correct (Above) or not allow the trading to continue (Below). Of course, somebody could exploit that to scam others, so they can be tagged if they've been caught scamming, and then they will not be able to trade for a certain amount of time. That makes the system work, and have some teeth on it. I will probably think of ways it can be broken, and then fix them.
