Human nature (we are scum)
A few years ago a colleague of mine was looking to have some building work done on his house. He got quotes from three builders, as is advised. Then my colleague's wife went to work at her job in the local courts and looked up each of the builders on the court computer. Two of them had County Court Judgements pending against them so they went with the third one. My colleague told me this as though it was just a clever use of the resources available. This is why nothing should be in a database accessible to civil servants unless absolutely necessary and access is fully audited and access to data not required for your job is an instant criminal conviction.
I hear they share ISP browsing history records with council employees these days.
