They have an ANN thread but I don't see the creator of the thread tagged with negative trust. From what I observed you guys usually tag them if they plagiarize content in their whitepaper.
You are correct but sometimes DT members give them time to respond to the scam accusation before carrying out any appropriate measures. If they ignore the accusation then should get tagged right away.
And since the scam accusation was made about a week ago and they ignored it. I am going to be the first person to tag. Thanks for bringing this issue up.
