Does a feedback or rating system for sell/buy transactions exist on this forum?

On the old forum we were able to rate transactions or give buyers and seller props for good transactions and the occasional bad transaction. This was one way to filter out the trolls and to validate legit transactions and also allow other members to make transactions with some assurances.
I’d rather be able to look up a user profile to see his/her feedback.
If not do we just post on the seller’s post and like?
Another question… I am trying to use tags but maybe I’m not doing something right?

Unfortunately Discourse does not have anything built-in or any available plugins to accomplish this. As a work around I created a Trader’s Feedback Category: About the Traders Feedback category
