"Revolut, in common with traditional financial institutions, uses algorithms to identify money laundering, fraud and other criminal activity, but unlike the rest of the banking industry, Revolut's algorithms additionally trigger an automated suspension of accounts. Revolut explains that "the system is programmed to temporarily lock an account and place it in a queue, until one of our compliance agents can review the case".
In September 2022, Revolut confirmed a cyber attack exposed personal data of tens of thousands of users.
The above should not deter anyone from at least considering the likes of Revolut as a banking option.
