Show HN: Simple JavaScript VPN detection using timezones

Seems to give false positive on Windows 10 as in my Date setting on OS level time zone is selected as something like Helsinki, Sofia, Kyiv, Tallinn, etc. (UTC+02:00) so both Firefox and Chrome reports it as "Europe/Kiev". While I am in a different country so IP address obviously reports differently. I wonder if it was thought about timezones where a lot of small countries can be in the same one.

Got a false positive in Taiwan because your IP lookup service provider (https://ipapi.co/json) returned no timezone.

Another false positive. Really simple one. Browser timezone Asia/Calcutta and IP timezone Asia/Kolkata ... The city changed its name a very long time ago and both the names refer to the same city.

Looked like an interesting idea, but seems like there are many reasons for false positives.

False positive, I’m in Copenhagen, but my browser reports Oslo.

It's a clever thinking, but only for vpns in other countries, the solution would probably fit netflix and other streaming services.
