Well I don't think VPN will be the last option considering the fact that using a VPN could greatly affects the game processing since quit alot of data will be required to run an external VPN and this can affect the overall gaming experience in a negative ways, since it slow down you network and even eat dip into your internal device processing system.
I think if there is no much thing as regards to regulations, if it be left for casino site, approving a country from ban list is easy since that is another way to grow their market.
Using a VPN can be a hassle, it's a trade-off that I'm not willing to make.
I'm starting to wonder if reaching out directly to the casino's support team might be a better option. Perhaps they could provide more specific information about why my account is restricted and if there's a way to resolve the issue without using a VPN. I'll give it a shot and see what they say.
I feel like compliance with local laws and the recent crackdowns here in the Philippines might make that process a bit more complex, especially with foreign operators under scrutiny.
