But I saying for why not it's shows on the user profile ?
Honestly, most users don't care about their DT status. They mostly don't care about it themselves but other forum members care about it. Is it necessary to pay attention on status that does not belong to yourself, I really don't see this need.
I only care if one member is scammer or not scammer and it can be seen with negative trust score and negative trust feedback that is enough.
