Suppose if I buy something from a user in this forum ? And after the transaction and trading am I supposed to ask him to give me a feedback in my profile ? And doing it, how do you see this ?
If you're trying to do such thing then its called trust farming and that is not how the trust system is supposed to work, if the other party feel that you are trusted for future tradea then they will do it on their own.
Many people got such kind of trust ratings in the past now DT members are aware they should not do it until you have clean sheet of trading history with no issues for a while.
