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 trade with someone and the person who traded with you thinks you deserve feedback, then he will give you feedback. You don't have to ask for it. If you do good work and present yourself as competent, others will judge whether you deserve feedback or not. Asking for and giving feedback on small trades like this is often seen as questionable. Because your account is visible to thousands of users, anything suspicious here will be easily exposed. Only feedback given by DT member will show on your profile, other feedback will not show on your profile. And when DT members give you any feedback they will give it with proper reason.
