About Fingerprinting.com and other tracking companies, it is good to keep in mind how they work.
They use uses state tracking (cookies, etc.) and IP and fingeprinting to re-identify users.
This is easy to fool on the surface, just e.g. resize your window before going back with a sanitized browser and new IP- but fooling is surface only.
Data collected can be weighted on the backend to re-identify a user.
Beating fingerprinting.com, because we have managed to fool it on the surface - is probably fooling ourselves in a false sense of privacy.
