Security measure ? I don’t understand what kind security measure, I can insert any kind of address and you can’t know if it’s fake or not. Also many times security and privacy go together, I don’t want say to kaspersky where I live.. I just want a license number, it’s absurd! Also you say that “no merchant will authorize online trasactions nless they can verify the validity of information used to make a purchase” -- This is absolutely fake, I buy a lot of things online doesn’t need of my home address and indeed they don’t ask for it. I bought rooms in hotel, vpn account, email account, airbnb and many other things and they didn’t ask for my home address. The other my question are sarcastic and just to expose how much time I lose for your absurd request. Finally I didn’t buy the license. Are you happy ?
