If I am not wrong usage of VPN os not restricted in Roobet but since your country is on restricted list you can't able to and you should not bypass the restrictions by any means like VPN or else your account will be blocked and all your funds will be frozen forever.
Correct, however you need to go through full KYC if you want to use VPN in non restricted countries. There's no reason at all to use VPN since you're already completing the KYC tier 1, this only for gamblers who have a problem with their ISP.
Woohooo didn't know Marlon Vera become a Roobet brand ambassador, it would be better if Roobet can reach Oliveira or McGregor since they're very popular on UFC.
