What a pile of c**p!
There is absolutely no need for the BBC to reply any sort of 'detector' anything... they already have every detail the need, simply because you logged into iPlayer. Even if you have a 'shadow' email/iPlayer account, they know everything about your Browser and the IP address you are using. It not a huge job to associate an IP address with a property address ... companies like BT Openreach & cable service providers log whiich IP address is allocated to their customers homes every day.
