I do not have him in my trust list and have not excluded him therefore the trust did not show up, thank you for pointing it out

The feedback they left for each other is still there. There is no indication that pooya87 even knows about this thread but keeping that aside, his is not the only negative feedback based on political belief or an ideology some would (and would not) agree with. From what I can see, both used the feedback system incorrectly and both should consider removing it.
Check if you cannot see the feedback due to exclusions in your trust list (you don't have to have excluded him directly).
