Internet reports that a man in the United States has sued Citibank for failing to prevent a $20 million encrypted "pig killing plate" scam. The plaintiff claimed that he met a fraudster with a false identity through Facebook and was cheated of his funds after investing in the NFT platform "OpenrarityPro". Citi was accused of handling 12 suspicious transfers totaling approximately $4 million, without identifying risk signals. The complaint alleges the bank grossly failed in monitoring and censorship. The case has been filed in the federal court in Manhattan, New York.
