Re: The IP address is not a great way to decide validity
If I recall correctly I was connected to a VPN server in France when I signed, despite being physically located in the restaurant at my local health club in Bracknell at the time. No doubt my signature would be on this list as a result.
Should that make my signature any less valid?
Your signature should be invalid because you were sitting at a health club restaurant in Bracknell and connected via a VPN server in France.
