Yes, You may use VPNs but only if the IP is residential. Note that using VPNs is not recommended. Why? Because if you use a VPN that gives residential IP and others use it too, with the same IP, it might be marked as non-residential IP. And then you don’t earn – you won’t get traffic at all. You will see a notification for bad IP addresses in the dashboard.
If your IP is banned, it probably has a low-quality score. You can try to change your public IP address.
NOTE: BrightVPN is not supported
