According to the Odaily Planet Daily report, on-chain detective ZachXBT stated that MEV engineer @pokerbrat2019 (namely Robert Robb) was arrested in Las Vegas. In December 2023, ZachXBT published an article exposing how Robert Robb stole more than 1.2 million U.S. dollars from 11 people and his criminal history of fraud. ZachXBT said that although it cannot be determined until the court documents are released, it is suspected that there are other reasons for the arrest.
In December last year, ZachXBT said that PokerBrat raised at least $1.2 million from 11 people for various MEV bots and claimed that these bots would be put into use soon. However, after initially agreeing to return the funds, PokerBrat made various excuses. PokerBrat previously pleaded guilty in 2002 after defrauding investors of $4 million, and was sentenced to three years in prison for fraud in 2007 after stealing funds from more than 10 victims in Colorado.
