To say that someone should not have trading experience to be in the DefaultTrust network is ridiculous. If they have no experience trading then what would they be doing looking at marketplace threads where the scams are going to be taking place?
No, not having trading experience shouldn't be and is not a disqualification from being on DT.
Yep, how come trust is developed only by doing trade? I used to trust Quickseller once, not because he had done a lot of trades, but because he was great in busting out scams.
The reason I came across the scams that I was able to bust was because I was active in trading. So although trading may not have been the direct reason for such trust, however it did play a roll (at least behind the scenes).
Also the scams I busted were not quite as obvious as the scams that the person who gave negative trust to the OP harasses about. I also don't go around in threads of scams posting repetitive information in an obsessive, and harassing way. I will warn others about what I believe to be suspicious behavior, and if someone has any questions or wants clarification, then I will most likely provide answers/clarification. I won't however accuse anyone who chooses to do business with a scammer to be a shill of that scam site, and the same is true for whoever chooses to take the risk of doing business with a likely scammer (although there is certain criteria that would make me believe that someone is actually a shill/alt of a scammer, and the OP does not match this criteria IMO)
