BE CAREFUL WITH THE BUYER BabySharkBTC

To avoid losing money due to price discrepancies, sellers need to be cautious of the tricks used by this buyer named BabysharkBTC.
In the USDT buying advertisement section, this person created 3 ads with 3 different buying prices of 25,016, 25,743, and 25,745 => Why is that? In fact, they have engaged in fraud and calculated from the beginning by deliberately creating the price quote of 25,016₫.
The issue is that when you set the spot price at 25,745 and confirm the sale, through some trick, the buyer will convert it to the price of 25,016₫. When discovering that the trading price differs significantly, the seller has no way to cancel the order. Thus, after the buyer has paid and provided proof, P2P will protect the buyer and will not address any rights for the seller.
The question arises as to why this BabySharkBTC buyer is deliberately creating price discrepancies and has been negatively rated by many sellers similarly, yet this account still exists.
