The OP has not posted for a week therefore we might have seen the last of him but if he were to return I would ask some questions.
Why is trust so important to you?
Whether you posts as a newbie with no trust/feedback or whether you post with several green trust/feedback, why is it a prerequisite for you to post? As you have already shown a defeatist attitude in previous posts stating effectively you cannot contribute therefore what is the point of you being a member here?
If there was an invite system it might have benefits but could be misused, the forum seems to be working well without it for all these years.
So you're telling me that trust built in long-lasting relationships matters less than the trust earned by trading with other users? 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.
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.
