Virtual Private Network (VPN) servers are proxy servers that people use daily when browsing the Internet. They use it because it shields them from being tracked by websites. As most of us are aware, websites track their visitors for advertising and marketing purposes. That’s how they can serve ads across multiple websites. By using a VPN when browsing, that no longer happens.
That’s the same reason that people use residential proxy servers. As residential proxy servers are actually home computers that are used by real individuals, websites have a much harder time differentiating between a real user and a proxy user.
