I don't think dispute resolution service can work here. I saw only real trade and scam trade. For any of these trade cant help resolution service. Mediation Services can be helpful to avoid scam. So, starting Mediation Services can be helpful for the community.
I disagree, as I have seen many cases of otherwise trusted members who either have a miscommunication, some how caused offense to each other, or have some other disagreement with details of an agreement that could benefit from such a service. Often I find people engaged in conflicts that end up hurting both parties more than a mutually restorative solution, and mediation from a disinterested third party can often help put egos and tempers to the side in order to reach maximal benefit for those involved. Thank you for taking the time to provide feedback nonetheless.
