You got a source for that?

One of the ways VPNs work is by having all your web traffic look like it’s coming from somewhere else, obscuring where you’re really from. They will see a different IP address than what yours actually is. If you were the only person doing this there would be no problem, but VPNs only have so many servers so companies often know what IP addresses those are. What they see is THOUSANDS of actions being taken by a single IP address, so of course it looks like bots! It makes total sense to have some verification to help against DDOS attacks and bad actors.

And if anyone is unsure they can also have their immunization checked by their doctor (Called a titer test I think?)
