Some years ago I worked in $BIGBANK and auditor from $GOVERMENT told as to change street name property from textfield to dropdown (for all countries) to help them with fraud detection, and remove all diacritic characters from client names their new software don't like them.

I told my manager that they are idiots and I won't listen them, he was like 'OK, as I expected' never done anything about it, next auditors didn't mentioned it.
