How to spot GPO trade scams

Grand Piece Online trading scams are mostly pattern-based. If you check the value of every item and don't trust vibes, you will rarely get scammed. Here's the current list of patterns.

Scam 1 — cross-tier 1:1

"1 PCC for 1 Awakened Bomb" looks reasonable until you realize PCC is Collectable tier and the other item is Epic. The real ratio is roughly 1:50. Our solver auto-rejects trades where items are two or more tier letters apart with no compensating mods.

Scam 2 — unpaired prestige

Prestige items (PCC, PFL, PWE, PIRB, PChak) are roughly equal in value but not identical. Taking 1 PFL for 1 PCC loses you around 40%. Always pair prestige items with the correct partner, not just any prestige item.

Scam 3 — hidden adds

"Adds" in GPO means extra items thrown in to balance a trade. A trade like "PCC for PFL + adds" is meaningless without specifying the adds. If the other trader insists on staying vague, walk away, or ask exactly which items the adds are.

Rule of thumb, from our learned adds values per tier:

• Low tier trade (~5K total): adds ≈ 1,500
• Mid tier (~50K): adds ≈ 16,000
• High tier (~200K): adds ≈ 57,000
• Prestige tier (~1M+): adds ≈ 250,000

Scam 4 — new-release bait

Items released in the last 30 days are volatile. Scammers lowball early while values are unstable. Always check the "updated" timestamp on our values, and use the range, not the point estimate, for new items.

Scam 5 — fake urgency

"Leaving in 5 minutes, trade now or I'm out." This is pure psychological pressure. A real trader who wants to deal will wait a couple of minutes for you to price-check. Ask why the rush, and the scam usually falls apart.

Rule zero — DM-to-DM exclusives

Marine Cap, Marine Cape, and Cool Shades almost never trade in public channels. If someone offers you one for a "reasonable" price in a public trade channel, it's fake. Verify through a trusted private channel or the item's known holder list.
