Sorry for the dumb question but then how are you defining spoofing in your tool? I mean, how are you seeing and prefer people see and understand the difference between your tool and what a VPN does? I’m guessing the means through which both try to obfuscate your IP/location is different and that’s how?
Assumption being that IP address and your time zone being different means you’re in the time zone and not really with that VPN IP address. So, I would not say the VPN has no effect but the VPN does not stop the website from inferring this info. Slight difference but an important distiction if you ask me.
Hah! That’s literally what I was thinking too - as to the real use case for such a tool.
