CFC/CPO - DO THEY EVEN KNOW WHO THE SHAREHOLDERS ARE?

Given reports in the press that the CPO shareholder database is so out of date it includes people who have died, is it fair to suggest that no one knows who is and isn't a shareholder?

Take my case, I've moved house a few times, including stints overseas since buying my shares. I have no idea where my certificate is (last seen in the middle east in 2003). When I phoned to asked for proxy vote papers I was just asked for current address and sent them, there didn't appear to be any check in place that I am a genuine shareholder.

Now I have received my papers and there is no shareholder or reference number on them.
Do they know who actually is/isn't a shareholder?
