Other DT members have been removed for scamming as well.
This is one of the reasons why DT should be removed completely. Scammers will and have found their way on to the list. The fact that there have been scammers on DT proves that DT isn't to be trusted, and the perceived trust is largely an illusion. DT list should only be a "people unlikely to scam others" list, and being on the list should signal nothing else.
