Review a member

Good idea though there's already a feature similar to what you're referring to. We already have a vouch system where you can check if the user has positive/negative vouches with comments included regarding how the deal went. You can check it on the user's profile: https://nulledbb.com/vouch.php?uid=2579

I think what NBB needs to do is make the vouch system more noticeable so that it will be utilized more often to help when about to deal with other members of the forum.
