Re: The IP address is not a great way to decide validity
Maybe the Vatican runs ISP and proxy services? Maybe the Vatican has licensed out some of its allocated IP numbers? Or other such explanations.
That would seem broadly equivalent to some of the places around the world - from Moscow to Minneapolis - that IP location services have placed me without any such thing as a VPN.
The referendum was gerrymandered, not least by reneging on the 2015 manifesto commitment to enfranchise Brits long-term abroad (as I pointed out back in February). If the same happens to this and other petitions, shouldn't that just be seen as par for the course?
