Not sure if its suggested before, but would be nice with a feedback system.It's like a "vouch". If you/him do a trade / job / service that youre happy with, you can leave a feedback.
Positive / neutral and negatives.
Also that you need to request the feedback BEFORE the trade / service is started, So its possible to leave a feedback if something goes wrong.
Or if all goes right, both parts can leave a feedback after everything is done.
Would also be nice if its not allowed to leave feedbacks on free trades / jobs / services, And have the Link to the thread where you request the feedback so it can be backtracked so other people can see if its a Free trade or not. So it wont be done lots of free jobs to get alot of feedbacks or something.
(seen this on another forum, and works pretty good. might prevent scams in the future. also, not all scams ofc, but will be less scamming perhaps?)
Something like this (from another forum tho):
