Always be careful using a VPN even though they say they are friendly to VPNs, of course in the future it will be a different story, so now there is still a solution, namely mirror sites can still be accessed without a VPN, because some casinos have their mirrors.
Once a casino promote themselves to be VPN friendly, there is no need to worry about using VPN. If they blame us or make a story up later due to the use of VPN while in fact we do not do something against the other terms, the casino should be responsible for it. Coming to mirror link, yes it is useful for those who have an issue with ISP but it may not work forever because once the ISP aware about the mirror links, it will all be blocked so players will need to wait for the casino to create new mirror links.
