OTC Trading Fraud Prevention Guide
Some criminals take advantage of OTC transactions to commit fraud. Here is a list of the most common forms of deception, and what investors can do to avoid them
Fraud Pattern
1
Fake Bank Transfer SMS Notifications
Fraudsters will send fake screenshots of bank transfer/deduction SMS requests, urging sellers to release coins fraudulently.
Fraud Pattern
2
Multiple Orders of the Same Amount
Fraudsters will place many orders of the same amount from multiple accounts. They will often click "paid" for one or more of the orders, without paying, but still urging the seller to release coins.
Fraud Pattern
3
Payment Amount does not match Actual Amount.
For example, if the payable amount is 11111 USD, the actual payment will be 111.11 USD. This confuses the seller and they may release the coins without realising the difference between the payable amount and the actual payment.
Fraud Pattern
4
Call the seller to let them know that the money has been sent
After a merchant has placed an order, the fraudster clicks on "pay" - but they do not remit the money. They trick the merchant by calling them and informing them to release the coins as soon as possible. The merchant may confirm the order by mistake when they process a large number of orders.
Fraud Pattern
5
Coins received, but a refund is requested
In this case, the seller has to prompt the buyer to verify whether the coin has been received in the Account Assets section. If the buyer insists that the coin has not been received, please wait for official customer service to intervene in the process.

Fraud Groups Collaborate and Impersonate Official Customer Service
In this case, the buyer accepts the order but does not pay. During this time, someone pretending to be the official customer service asks the seller to release the coin immediately, or to transfer the coin to a specific address.
Fraud Pattern
7
Remittance of Double Cooperation
Users A and B simultaneously place an order of the same amount. User A sends their money to the merchant, while user B does not. User B will pretend to pay and calls the merchant to inform them that there is an issue. This pressures the merchant to confirm the order quickly, without carrying out any due diligence. When the merchant checks the collection record, he might confirm both the orders by mistake.
Fraud Pattern
8
Entering the Wrong Merchant Card Number Intentionally
When filling in the merchant's bank card number, the fraudster will intentionally fill in the wrong numbers and take a screenshot of the ordinary remittance record. Some bank remittance records will hide several numbers. The fraudster will click "I have paid" and then urge the merchant to confirm and release the coin. The merchant may click to confirm receipt and releases coins without checking the remittance information properly.

Middleman Fraud
（1）The fraudster contacts a seller and claims they want to buy coins - this requires the seller to place an order. Simultaneously, the fraudster contacts a buyer claiming that they want to sell coins. He asks the buyer to go to the OTC designated order and place an order to the order that the seller has just created.
After the buyer places the order, the fraudster requires the buyer to remit their money directly to them, rather than the original transaction address of the seller. The same process is followed for fraudsters who claim they want to sell coins.
1) Please do not trust any social media chat contents. All the user information provided by the official website shall prevail.
2) Don't trust anyone who claims to be an official person from ZB. If you have any queries, please contact the official customer service.
3) Please check the payment information carefully, and confirm that the payment is the correct account.
(4) Please carefully verify the amount of each payment, especially noting the decimal point in the amount.
5) Remember that everything is subjected to the bank flow of the receiving account. Text messages or screenshots can not be used as the basis for remittance.
