Some websites detect and block VPNs to prevent you from violating their terms of service. Your VPN is more likely to be blocked if you use a free one. That’s because it’s likely to have overcrowded servers and mostly blocklisted IP addresses.  Opting for a high-quality VPN provider that regularly checks its IP addresses is a good way to bypass content blocks. You can also get a Dedicated IP address, which is an IP address only you can use. If nobody else uses your IP address, it’s less likely to be detected and blocked.
