Question [Q] Can Google block a device?

Hello,

If asked can Google block a device by its serial number to prevent it from ever being allowed to use Google services?

If so, does that mean Google can help users locate a device if it is connected to a WiFi? whether from existing user account or from a new Google account?

This doesn't only apply to a stolen devices but in case a seller decide to screw around with a buyer of a used devices.


Would appreciate some feedbacks.


Thank you.
