For a scammer tag, the accused person needs to have promised to do something and then failed to deliver on the promise. TradeFortress never promised to pay anyone any bitcoins here. If you trust him to do something that he didn't promise, that's your problem.
OK, if 3 topics and lots of people probably scammed aren't enough, i have to follow your argument:
from the first post in TradeFortress topic, everybody can read he encouraged people to withdraw HIS ious at a gateway. But this isn't possible, not every Bitcoin issued by TradeFortress is withdrawable at a gateway.
