Well well, I guess it's all clear now, to avoid users like you blackmailing other users on this forum is the reason why the DT was introduced, whereas if you are not a DT member, your trust feedback, be it positive or negative is completely useless to the forum and other users because no one, except yourself; sees that feedback.
Like for example, right now, I can't even see any feedback of yours in the two profiles you shared here in your comment, which simply means that your feedback, trust rating (calling it what ever you want) is only visible to you and you alone, even the profiles you posted that rating to can't even see it until you become a DT member.
So, my advice, stop wasting your time bud, you can't Blackmail anyone on this forum using negative trust as a bait, if you feel you were cheated by this casino, go to scam and accusation board and write a proper scam accusation thread against this casino providing all the necessary evidence/proof, if the DT members find your allegations true, they will Tag this profiles with negative trust on your behalf.
