Getting the trade off the record
Almost every scam starts with a reason to move the conversation somewhere it is not being recorded. The reasons offered sound reasonable — faster, easier, a discount for paying directly, a problem with the platform — and the effect is always the same: whatever is agreed next cannot be shown to anyone.
The habit that defeats this is simple and absolute. Every agreement about price, amount, timing and delivery goes in the order chat. If someone will not agree there, they are telling you they need the agreement to be deniable.
The discount-for-paying-directly version is the most tempting, because it looks like the seller is sharing the fee saving with you. What you are actually buying is the removal of the escrow hold, which is the only thing standing between you and a seller who takes the money.
Partial delivery and premature confirmation
The second family targets the confirmation step. A seller delivers part of a large order, then asks you to confirm so they can 'release the rest', or claims the platform needs the confirmation before they can continue.
It does not. Confirmation exists to release money to the seller and nothing else, and it happens once, at the end, when everything ordered has arrived. A request to confirm early is a request to be paid for work not done, whatever explanation accompanies it.
The same logic applies to services. You confirm when you have logged in yourself and seen the cape, the level or the quest completed — not when you are told it is done.
Fake middlemen and impersonation
A recurring scam offers a 'trusted middleman' to hold funds, sometimes impersonating staff of a platform. There is no scenario in which a legitimate escrow trade needs a third person holding anything: the platform is the escrow.
Treat any private message claiming to be support with suspicion, particularly one that arrives unprompted and asks you to do something. Support does not need your password, and no legitimate process involves handing an account or funds to an individual to hold.
Chargebacks, aimed at sellers
The scam run against sellers is the reverse: pay, receive delivery, then reverse the payment. Sellers taking direct payment from strangers wear this loss in full, because the gold cannot be un-traded.
The defence is structural rather than intuitive. Deliver only against funds already moved out of the buyer's control and held, and let the release happen through confirmation. A promise of payment, however convincing the buyer seems, is not payment.
The short version
Keep every agreement in the order chat, confirm only once at the end, and never deliver against a promise. Nearly every scam here fails against those three habits.
