So you're telling me that trust built in long-lasting relationships matters less than the trust earned by trading with other users?
The two aren't mutually exclusive.
That's great! I guess I'll go farm the so-called "trust" by doing small transactions with other users until I collect just enough to do some nasty scam, only to remind y'all that Goodhart's law exists.
Wow, you must be the first person to have ever thought up this idea. I'll give you a piece of friendly advice: announcing plans to scam the community isn't a great way to build a reputation here.
The way it works on this forum could be far better if we had some kind of "invite" system that wouldn't prohibit newbies from posting but would require oldfags of the forum to vouch for them to ensure that the newbies would act in good faith. That would be far less time-consuming for newbies and far more similar to how trust in the real world works.
That's more or less how it works now. Visible trust (default trust) can only be given by members that are part of Default Trust (DT1 or DT2) -- aka members that have been a part of the community for more than a minute. It doesn't have to be given only for trades, although that is largely how its supposed to be.
