Revolut AI failures

Revolut's Sherlock fraud system autonomously froze thousands of accounts without adequate review

Revolut's machine learning fraud detection system, Sherlock, autonomously flagged and froze customer accounts based on suspicious transaction patterns, often without sufficient human review before action was taken. Thousands of customers reported being locked out of their accounts for extended periods with no emergency phone line and only an in-app chat function for resolution. Lithuania's central bank fined Revolut €3.5 million for AML compliance failures, citing over-reliance on automated systems at the expense of human oversight.
