Initially thats what I was hoping to achieve.
Not true because the user with the DNT would not have any access to any form of trading. As with the current TWC rank, they are able to post in the account section and what not. With a DNT they'd only have access to important areas i.e. General discussion and no PM privileges/marketplace privileges. This would prevent them even scamming. If the user can't access any trading area's no scams would go on. The majority of end users are smart enough to get proof of people's OSBot accounts so I highly doubt this would be an issue.
