I don't know what's the reason why we need to leave positive feedback when there's no money or trade involved?
The forum's recommendation is this:
Positive - You think that this person is unlikely to scam anyone.
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.
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.
Even I see many people also giving you positive feedback without money or trade involved.
Or the other way around: some of the largest amounts I've handled for others didn't result in any feedback. Not that it matters much, because it's usually with Newbies who's feedback is "Untrusted" by default.
"This user is really valuable and wrote many high quality posts, it's an asset in this forum"
That would be
really hard to fake.
"This user fighting against scammer, good scam buster"
I've seen this go wrong several times: users quickly gaining a reputation and positive feedback as "scam buster", and eventually scamming when they see an opportunity.
"This user is a good guy, useful, and active in x board"
I think this mainly happens on local boards.
"This user is trusted with his valuable posts"
This could apply to technical posts: it's good to know who's posts are generally correct, especially if a Newbie were to ask a question and gets opposing answers.
"This user is really smart about Bitcoin"
Lol. This requires a very convincing Reference link.
The good thing about feedback is that you can read it and decide on your own if it means something to you. If someone had the chance to steal $10,000 and didn't scam, I'd say he isn't likely to steal $1000 when he gets the chance. But if someone's posts on a local board are highly valued by his fellow countrymen, that doesn't tell me if he'd run off with the $1000 once given the chance.
I feel those above positive feedback isn't correct, since there's nothing about money or trade involved.
If that's how you feel: exclude the users who left that feedback from your Trust list.
Why does a smart person which created many high quality posts can be trusted?
It depends: I wouldn't necessarily trust them. In fact, there are only a few users here who I'd trust with any significant amount without thinking about it.
But think about what someone has to lose. I recently received a PM from a Newbie saying he doesn't want to be conned, and I'd be an idiot to do it because my reputation is worth more. He's right. That's what gives a reputation value.
it's just like trusting a hacker which know how to hack a website and stole the funds.
I wouldn't trust a hacker who steals. But a hacker who informs you about a vulnerability
can be worth $50 000.
Now talking about scam buster, a respectable person who help the forum, why we should leaving positive feedback a respectable person?
I wouldn't do it. But some users do.
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.
Moreover trusting someone because he active in x board, knowing each other or join on a same gang/activities e.g. active in their local board are just subjective judgement and shouldn't given a positive feedback.
Agreed. This is one of the reasons why many local board members have so many Trust exclusions. So the "voting" system works.
tl;dr trust feedback is used for money oriented
Read this again:
Positive - You think that this person is unlikely to scam anyone.
Positive feedback can be based on your opinion. And it's up to others to decide whether or not they value your opinion.
