There is no excuse to 'go fishing' for any reason and whilst the release of certain information about a Company Director is demanded within the UK Company Law system, there is no requirement to release additional data and the Board do not choose to do so.
Correction, there is no *legal* requirement. There is a moral requirement that people know who it is representing them. As I understand it, Paul will have to stand down at the upcoming AGM, since he was appointed not elected. Assuming you actually allow interested parties to take part in the AGM (if you don't, you can expect trouble), I strongly doubt he'll be elected without telling the electorate a little more about himself. His on-wiki identity, at the very least.
