> What is the return-time between a ping (or similar) from the BBC to you and back? If it's over a certain number of microseconds, you're 'no longer in Kansas, Toto'. High latency can be legitimately expected over mobile or satellite connections, it's not a strong signal of a non-local user by itself. UK has real shitty broadband in most places in comparison to 4G/5G, I'd expect a pretty large share of mobile users there. You could also be using an app like youtube-dl or streamlink to record the stream from a nearby VPS with low latency.
