I was wondering if it's possible to chain many VPNs, and if it is, if it increases privacy at all?
My thinking was that each country has data retention laws. If all VPN keep logs (even if most lie about it), they are only required to keep them for a certain period of time. And by chaining VPNs you would make it harder for authorities to find you because they have to get a court order fom each VPN, right?
So initially they only see the IP of the last VPN. They contact them and ask them for the logs, they refuse until they get a court order. This takes some time, but they get it and contact the VPN. The VPN gives them the logs and now they obtain the IP of the next VPN and so on.
So when they finally reach the last VPN and get that court order for the logs, its data may have already been deleted due to the limited data retention rule.
Does anyone know if this is the case? I've seen this kind of scenario in movies (the chaining thing)
PS: I'm talking about VPNs across different countries. If they are from a single country I guess it would be very easy for the authorities to quickly go through all of them because they control the legal system there.
