I don't think it's redundant at all. When a bank examines the details and banking history of a client, they examine data containing both good and bad points over the years. The bank then makes a decision about that individual. This is part of KYC and AML. However, the client also︀ has a duty and even an obligation to do their own due diligence. This may︁ involve public data such as market capitalization, profit, liquidity, history of CEO etc but also︂ information gathered from other sources. Websites like this one serve as a very important source︃ of such information. Since the fiasco that was the Great Financial Crisis, a client's KYB︄ and AML checks are more important than ever. Simply do an internet search for 'bank's︅ name' + court+ fine+ corruption+money laundering...etc and you see what I mean.
