[entwisi]

When I did mine I had to provide info on where I had worked, where I had lived, any criminal convictions including motoring pointsand something else that escapes me at the moment. These are sent away and your past is double checked (I know as someone I hadn't seen in 10 years told me that they had received a call about me when I bumped into them in town)

As you said though, any accusations wouldn't come to light unless someone mentioned them and even then I guess it would only be hearsay
