Have you tried to gamble via VPN ever? Do you realize it is a flag by itself because the IP addresses are known. It will take years to block and know VPN addresses realtime for states. But the security departments of gambling companies know it as those lists are known to ad-companies who do not pay for clicks/impressions from VPNs.
And playing via VPN from idk UK when you are in Australia means that you will most likely never pass through the security at the sportsbook.
The gambling corporations are simply not able to accomodate (yet) to the world of VPNs (there is a friction between the affiliate [who should want that traffic ] and securty department [ who is scared of it ]). There were exceptions like bitcoin bookies and 1xbet, but once VPN is allowed the gates to frauds are open.
If you talk to God, you are praying; If God talks to you, you have schizophrenia.
