That can very well apply to long-term community members. I think a reputation of being good with thousands of hours spend on this forum means someone isn't likely to throw that all away for a quick buck.
I understand, however it depends on the users itself. If I trade with a chipmixer's participant, I wouldn't think twice before send my funds to him since they're got $300/week. He wouldn't scam only for $1000, that's amount might be a peanut by him. Can a bounty hunter especially never earn any single merit and spend a lot of times to shitpost deserve a positive feedback? jk.
It is much easier to get positive trust by buying something on the Collectibles board, and selling it again. Even better if you pay some of the usual escrows there, you may get 2 positive ratings for only one trade. It's up to every forum member to decide for themselves how they value this.
Yeah I also noticed that, however a reputable user wouldn't easily give a positive feedback even you've done multiply trade with him. Personally I would think when the user leave a positive feedback for low amount trade it's not really correct isn't? especially for a brand new newbie, some people might think he's safe to trade without an escrow.
If that's how you feel: exclude the users who left that feedback from your Trust list.
To be honest this is the another problem for me.
Those users who left a wrong feedback also left so many correct feedback, it would be unfair if I just looking his single mistake but I didn't care with so many contribution he do for this forum. If he got excluded from DT network, his negative feedback to scammer will be shown in untrusted feedback. If the scammer only got a negative feedback from this user, anyone wouldn't know this scammer is a scammer since his trust will be neutral +0 / =0 / -0.
Also excluding an user isn't something easy to do, I've seen many members had a conflict because of this. Distrusting someone doesn't mean I don't like your post, I won't merit your post or I hate you, but I just don't like perspective of giving a feedback due to personal interest. Usually when A distrust B, B will distrust A too and B will search anything wrong have been done from A e.g. cheating with multiple alts, plagiarism etc.
I don't think that user deserves 10 positive feedbacks for this, half of which is from DT. He got one from theymos, and in my opinion that should have been enough.
Agreed, a feedback from theymos have a good weight.
