They do have private and public VPN detection and enforce it actively. I have tested multiple accounts across paid and unpaid VPNs over the last 6 months. Don't tell me what you think you know about what I actually know. It's a complete waste of everyones time.You don't know what you're talking about.
MAC address is at no point exposed via internet.
VPN usage can be detected only if it's public well known one.
Linking IP addresses - ok, maybe. But one IP is always shared by many users - this is simply how internet works.
If there's a mod they can close this thread, absolutely pointless to continue the 'discussion' at this point.
Thanks - yeah it would just get too complicated switching between multiple MAC addresses running from the same computer, with different IP addresses for each. Honestly just easier to get a separate PC.Understandable.
If this is the only reason, be advised that a MAC address is easy to change, even repeatedly (the particular method/s/ depend on your operating system).
