1-DT members have to reference every feedback.
2-you CAN NOT red tag someone for being a troll.
3-all negative feedback has to refer to scam activities or account sales.
#1 is reasonable but it's hard to enforce. The link could be meaningless. You still have to look at all the facts to properly gauge the value of the feedback.
would still be better than no source of gauging at all
#2 would be solved by custom lists. If you don't want people to be red for trolling - don't add users who tag for trolling.
this is for my own perspective on others, but it does not work the other way around. if i get a negative for trolling, others will still see it regardless of my custom list. if i was selling something for example, i would worry more about the look of my profile than the look of other's profile, so custom list would be completely useless for one's personal trust page.
In the end, DT or custom list affects just the warning in a thread and on the main profile page. All (trusted and untrusted) ratings are still visible on user's trust details page and you should probably review all those before engaging in a trade with someone you don't know.
I agree 100% that people should evaluate trust feedback, but if we were to make a survey asking members whether they even consider engaging in a trade with someone who has a red trust from DT member, I will bet the horse that the vast majority will stay away the moment they see that scary red
" WARNING !" before even looking at who gave it and why, therefore we are being unfair to someone who may be very decent and honest with his trades but he got a negative simply for saying something that a mighty DT member does not like.
