There's nothing left for you but to convince one of your friends to login and try to ID verify himself,but I'm not sure that this will work,since he will have to login using a different IP address.
What if some representative of the sports betting website checks your login history and sees all those different IP addresses and VPN proxies?I'm sure that he will become suspicious and ban your account forever.
That's why using a VPN to access gambling websites is always a bad move.
Different IP addresses by themselves do not indicate that the user is violating something - there are many reasons to log into your account from different devices, places, and even from under VPN. I think the OP should carefully study this part of the TOS (something he didn't do before he started using this site at all) and then, unless there is a strict prohibition on the use of VPNs, use the help of a friend. I think you can always come up with a story on which the use of VPN will be justified.
