The only question that I have is "why we should belive this lists?! I also can be that ''honest'' traders, who is writting here just like you are, do you belive me? do you have any resons?
We shouldn't! All it tells us is that - at a certain point in time - X transacted with Y and the outcome was satisfactory (according to X and Y). All this represents is part of the process by which you establish whether X or Y can be trusted.
As an example, I transacted with another forum member several years ago, and we both posted here upon successful completion. But - since then I could have "gone rogue". And, of course, it could have been a scam by both of us to convince people we were both trustworthy!
Personally, I think this thread is useful (and was probably more useful in the past - it doesn't seem to be updated that much anymore), but shouldn't be the only tool you use in establishing trust.
