He is DT1, on my trust list I have "default trust" and I haven't ~Royse777 there. So, why I don't see his feedback in "Trusted feedback" when they are DT1?
I guess some are from my list distrust Royse777 and this was reflected what I see on user trust.
You can't have a custom trust list and have Default Trust. As soon as you add anyone to your own list, you no longer include Default Trust, even if you manually add "Default Trust" back in. See below:
If your trust list is totally empty, you trust "DefaultTrust", which includes some trustworthy people that I'll select. But if you add anyone to your trust list, even if they don't trust anyone, DefaultTrust will no longer be considered part of your trust list.
If you visit
https://bitcointalk.org/index.php?action=trust;full, you will be able to see exactly who on your trust list is either including or excluding any particular user. Looking at Loyce's site, it seems that you trust JollyGood, Coolcryptovator, and TalkStar, who all distrust Royse777.
