Maybe the seller can randomly generate a password that allows the other person to write a verified review. That way you prevent random negative reviews from people who haven’t even traded.

I back this request fully. Not only will it help single out negative traders and potential scammers but it would also reward traders with a good moral compass. Those with higher rating scores would be guaranteed to get more business.

a reputation would be awesome to have! account has to be atleast a certain age to stop abuse and stop the trolls

Comment from another user:

It would be very beneficial for the trading community to have the possibility to "rate" the trades between users after they have been completed. (similar to ebay or other platforms)

Think about user A selecting the trade that has been completed with user B on the website

user A provides a mandatory (Positive/Negative/Neutral) vote to user B, and might add additonal optional comments

user B recieves this feedback and proceeds to likewise provide feedback to user A

Only when both users finalise the process the feedback will be displayed on both user's accounts (this gives motivation to both parties to complete the process)

This info could be added to the user profile to see how many trades they have completed using this platform and the percentage of "happy costumers" they have had.
