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 ?
I'm not sure I can give a recommendation on how to earn trust in the forum. This is a very lengthy and difficult process that can take many years. In contrast, this trust is quickly lost. Even well-known and honored users of the forum can instantly lose confidence and even past merits will not be able to influence in any way.
The profile's feedback you're talking about doesn't really mean much. An
unknown user left a review for another
unknown user. What kind of trust are we talking about here? If an honored member of the forum leaves a feedback for you, then the situation will look different. But even in this case, there will be no guarantees that you have earned trust. Trust in a forum is something abstract that can't be felt or measured without talking about a feedback in a profile. It exists and is expressed in relation to you by many people.
