I can see all the electoral roll information from 1997 still up there with my old name, old address, phone numbers, age... None of that information I wanted public but there's no way to get it wiped far as I can see. The councils sell that information because voter information is considered public property at first, and then ends up in the hands of companies charging fees to look at it.
Good news for me is that name has no current association with me or my address - I've lived in 5 different cities since then, I'd still be very hard to find for all but those with access to my social security number.
