Dispute arbitration in practice, patterns from reader mail

The Bureau receives a steady flow of reader mail about disputes on Nexus Market. Most letters are one of a handful of patterns. This case study summarises the patterns, what actually happens after a dispute is opened, and what buyers can do to shift the outcome in their favour before a dispute is even opened.

Pattern one, the vendor ghosts

Buyer places order, deposit clears, vendor never ships and stops responding to messages. Buyer opens a dispute at the seven-day mark. Moderator checks the vendor's recent activity, sees the vendor has gone dark on multiple orders, cosigns with the buyer to refund the deposit. Vendor's bond gets partially forfeited if the pattern is widespread enough. Outcome for the buyer: full refund minus network fees, usually within seventy-two hours of opening the dispute.

This is the most common dispute type in reader mail. Buyers who opened disputes on ghosting vendors report the moderator response as quick and consistent.

Pattern two, the shipment is late but arrives

Buyer places order, deposit clears, vendor ships slower than the vendor's own advertised window. Buyer messages the vendor, no response for several days. Buyer opens a dispute at the ten-day mark. Vendor responds to the dispute (they had noticed the message system but had not answered), explains a shipping delay, provides some form of tracking or confirmation. Moderator waits. Package arrives. Moderator closes the dispute in the vendor's favour. Buyer finalises normally.

Outcome: no refund, no penalty. Reader mail on this pattern is often frustrated because the buyer felt the vendor should be penalised for the message delay. Moderators generally do not penalise for slow messages alone, they penalise for undelivered orders.

Pattern three, the product does not match the listing

Buyer receives the order, item is not what was advertised. Buyer opens a dispute with photographic evidence of the mismatch. Moderator checks the listing, checks the photos, judges. Common outcomes: full refund if the mismatch is clear (wrong item entirely), partial refund if the mismatch is a matter of degree (weight short, potency lower than claimed). Vendor's reputation takes a hit either way.

Reader mail on this pattern varies more in outcome. Buyers who provide clear photos and a clean message trail report favourable outcomes more often than buyers whose evidence is weak or whose message history includes accusations before facts.

Pattern four, the seller-favours-vendor complaint

Buyer opens a dispute, moderator cosigns with the vendor, buyer feels the ruling was wrong. Reader writes to the Bureau asking whether moderators are systematically biased.

The Bureau's read from the mail volume: no systematic bias visible. Moderators generally cosign with whichever side has the stronger evidence trail. Buyers who report unfavourable rulings almost always turn out, on inspection of their own account of the case, to have a weak evidence trail (no photos, accusatory messages before evidence, unrealistic complaint scope). Buyers with strong evidence trails rarely report unfavourable rulings.

This does not mean moderators are always right. It means the buyers who feel wronged are often not wrong to feel wronged individually, but the pattern across all dispute mail does not show a systemic problem.

What buyers can do before a dispute

Encrypt shipping details to the vendor PGP key at order time. Keep every message about the order polite and factual. Take photos of the package on arrival, unopened, with a piece of paper showing the current date visible in the frame. Open a dispute only when the vendor has failed to respond for at least seventy-two hours after a clear question.

What buyers can do during a dispute

Provide evidence up front. Do not accuse. State facts, dates, message references. Attach photos. Answer moderator questions promptly. Do not open multiple parallel disputes on the same order. Do not threaten the vendor. All of these hurt your case if they end up in the message trail the moderator reads.

The role of the multisig contract in disputes

The whole reason disputes work on Nexus is that the coin is in the 2 of 3 multisig contract, and the moderator's signature is the second one needed to move it. If the market held custody, the moderator's cosign would just be an internal database change and the operator could reverse it at any point. Because the moderator has to actually sign a multisig transaction, the settlement is durable and cannot be silently undone.
