Just to clear my doubt Please let me know
Is asking for a feedback is wrong??
You answer may be helpful and give me more information about the forum
I think no, you are free to ask a feedback as long as you have made deal with them and they willing to give you a feedback.
And You are free to give positive feedback to someone who has made deal with you as long as you trust them and that account is not your alt. It's better if you had reference link. The reference link means that the deal is in public.
There is no need for a trade/deal to occur to leave a feedback.
We don't actually have a trade feedback system; the reputation system that we use on the forum is a trust feedback system.

Many people who get negative trust complain that I have never traded with them and should remove my negative trust. This is an invalid argument.
