FWIW I don't see why DiamondCardz is in that default trust list either!
I'm not in the DefaultTrust list, I'm just trusted by someone who is in the DefaultTrust list.
...You're trusted by TradeFortress which makes you and your ratings be in the DefaultTrust list, just like everyone else in the list. You just have the restriction you can't add people on the list, TF can.
