According to CoinMeta, staff from the Commodity Futures Trading Commission (CFTC) pointed out in a recommendation released on Tuesday that 'mention' contracts in the futures market could be susceptible to manipulation. The settlement of such contracts depends on whether a specific individual uses certain words, appears in certain places, or interacts with others. The staff stated that these contracts should be considered vulnerable to manipulation. The recommendation mentions that the settlement of these contracts relies on the behavior of a particular individual and may not be independently generated or externally verifiable. The CFTC's recommendation does not have legal binding force and merely represents the views of the staff. It was issued after the CFTC reached a settlement with former White House speechwriter Gabriel Perez last month, who was fined $172,000 for trading on contracts related to presidential mentions.
