Splitting a group dinner bill, one friend jokingly added a note in the bank transfer memo referencing a bet from last night, just for laughs. Within half an hour the bank flagged the transfer for review and froze the account for a few hours, even though the payment itself was completely legitimate.

Automated fraud filters only read words, not context, so a sensitive term gets treated the same whether it is a joke or a real risk signal. The same pattern shows up on Binance P2P, except buyers are not joking, they write it because they think that is what honesty looks like.
Many buyers think writing "buying usdt" or the exchange name into the payment remark proves the trade is legitimate. Under Binance P2P's dispute resolution rules, sellers can require buyers not to include sensitive words like "crypto", "C2C/P2P", "BTC" in the transfer remark.

If a buyer accidentally includes those words, CS steps in so the seller releases the coin or issues a refund, but the refund fee is charged to whoever broke the terms, meaning the buyer. Vietnam's P2P CS team confirms this is a common mistake, not a rare one.

Self-critique: this rule only fixes the order-side problem on Binance, meaning who releases the coin, who pays the fee. It does not fix the bigger issue, the same one from the dinner story: the buyer's own bank independently reviewing or freezing the transfer because of that remark.
These two systems are completely separate, Binance has no authority over the bank's side, so a P2P order can close smoothly while the buyer still has to explain the transfer to their own bank afterward.

So Binance P2P should be evaluated based on whether the buyer read and followed the seller's payment remark instructions, not just on whether the transaction itself was honest.
