This prevents the feedback farmers to make unnecessary noise. There are users who will only get interested with The Pharmacist just to get a positive feedback since he is on DT.
That's exactly it. I'm very conservative when it comes to leaving positive feedback since I'm on DT, and I don't want a bunch of newbies or trust-seekers flooding my inbox with requests to trade because they think I'm going to leave them a positive trust--and that's been a real problem in the past (though for the life of me I can't remember an example, but I'm sure other members could).
Most of the time (because I'm
usually selling bitcoin) I'm the one bearing most of the risk in the transaction anyway, so it's not like the counterparty has demonstrated true trustworthiness. Personally, I'd rather all of my deals be feedback-free but I understand some members do want to build a trade history. Anyway, that's the reason.
Please notice- It's not an accusation.
No offense taken at all, my man. It's a legitimate question.
Edit:
By the way, I think my inspiration for including that phrase in all of my Currency Exchange threads is because I got scammed by a green-trusted member in 2016, and he had only one positive feedback from a DT member for a deal that was relatively insignificant. Believe me, you don't want to give someone a net green trust score unless they really deserve it, because some people just look at the color and think "this person is trusted"--which is exactly what I did when I got scammed.
