Dear Harry,
As far as I am concerned you are free to do as you wish, but all web-sites seek some small return for their efforts, even if that is only an acknowledgement of their existence. [Their name, and/or their address.]
I am fairly certain that the omission of these minor details in your post above is entirely accidental, and this is but a gentle reminder.
Oops, I did not take time to thank you Harry for availing us of the opportunity to have sight of such a detailed run-down of PB's history and achievements.
