Because DefaultTrust people are supposed to hand out judgement that would be seen by the rest of the forum by default. So, from natural logic, it needs to be handed to everyone doing the same thing, in the same way. Ponzis in disguise only turn out to scam, when they fail. When you are labelling a running program as Ponzi, relying on your "strong believe" and NOT labelling another one because of "no evidence", then you are acrually showing discriminatory nature, which is not supposed to be coming from people on DefaultTrust.

Because it is believed to be untrustworthy, not proven. Right now, you can leave any feedback, because you are not on DT. But, once you'll be on DT, you need to revise those feedback and be sure that you are not being partial to anyone, i.e. giving -ve to one but not to another for the same thing, which is the case in this thread, as I "strongly believe".
