Examples of competitors sharing data about bad customers across several industries:- competitor banks share information about people who bounce checks- competitor insurance companies share data about customers with fraudulent claims- competitor casinos share photos of card countersProbably many others I can't think of.EDIT to reply:  thanks for the customers' returns example.  I found a story explaining the shared database:  https://www.elliott.org/case-dismissed-2/the-retail-equation...
