Gotten warning message on official Pokemon Go APP in my new account, PF is detectable

It is pretty simple:

You are located in for example New York and your gps location is let's say Sydney.
The geo location of your ip address doesn't match your current gps location -> getting flagged.

If you change countries/continents like you are superman, flying with supersonic speed, well, you deserve to get banned.
I never understood people that told others "if you wait 2 hours it is safe to change continent", as it is just super stupid.
