While one Big Four seems to be diving headfirst into the ruder side of the business world at the moment, another is determined to make its cash with a more prim view of things.

As Ernst & Young messes around with Club 18-30 and porn publishers, Deloitte has launched a new audit service that detects illicit images being viewed on computers in the workplace.

The Irish part of the firm has teamed up with a software developer that can scan over 80 image and file formats for naughty pics in order to 'protect employees' from exposure to such wickedness. After all TS hears it can warp the brain and make you go blind.

Thank you Deloitte, you have once again saved the moral fibre of the nation. Now, when are you going to have a word with one of your rivals?
