VPNS don´t often work because they use a single IP address and you´ll have hundreds if not thousands connected to the same one. We know that See Tickets have a throttle for 60 refreshes a minuite per IP address so if you´ve got potentially hundreds all hammering F5 every second that limit is going to be used up imedietly.
So imagine you set you VPN to Spain or whatever and try that, you´ll already have probably quite a few people set to the same server in Spain hammering the See server .. Folks who thought exactly like you did .
You´re better off just getting as Many devices with different IP addresses as you can. So your home WiFI and different mobiles with different sim cards. Then get everyone in your group of 6 or whatever to do the same.
I usually have the wife doing the laptop and then our two mobiles connected to my work laptop and and her work laptop via hotspot . Then I have them sat out in front of me with the table and I press F5 between them with a second between each hit. 1 laptop, 2 laptop , 1 laptop , 2 laptop. While the mrs is doing the same on her macbook.
Another tip. I´ve found for some reason Safari is a really good browser. No, evidence of that, but i´ve always had good luck with it
