Exactly what I thought. Not the best idea to put the entire Openreach ONT serial number database public facing then.
It's good for confirming you have the correct ONT, but a partial serial number being shown would be enough, or a challenge asking you to enter part of the serial 1st.

I was hoping it was yourself answering that. Cheers Mr T 👍🏻
