It looks like some bean counting droid who thinks that RBS can save a few bob with not setting up an internal communications system by getting Farcebook to do it on the cheap. So, how long before:
* Bank details are shared via facebook
* Security secrets are shared
* The NSA gets hold of this information
* It leaks to people who use this information more publicly than the NSA does
* Someone at RBS is quoted saying ''we will learn from our mistakes''
