I think sitcoms online should do what gametz.com does for good traders and bad traders. then you would know who is a good trader and a bad trader.

I'm not familiar with how that site works, but we do have good and bad trader listed at the top of the page (The COMPLETE Bad Traders List & Recommended Traders List).

Sadly, I've often seen that many traders are content to let others post the good comments. Some traders consistently don't post good trader comments. Just as with eBay's feedback systems, the results are cockeyed, but this is the best we can do under the circumstances.
