I happen to know growstuff that that particular poster is Manchester born and bred and has lived there all her life. She has just had the misfortune to be stranded in Spain, due to COVID lockdown, since March of this year. She would have exactly the same access to information, first hand or not, as any other poster who happens to be currently living in another country, either by choice or circumstance.
And as for and probably from a selected group of like-minded people or the media, isn't that how most of us are accessing the news at the moment? Aren't most of us, especially those living overseas, relying on "the media" to provide us with the news, seeing as how we're pretty much confined to barracks? I'm afraid you're post has confirmed my suspicions.
