I'm not even familiar with TOR, I'm using default connection from my ISP. I guess I need to use VPN to fix this which is the same as what I did in the past when similar issue happened.
I would advise not to use a VPN unless it's an exclusive IP and hasn't gotten in the hands of anyone yet because there are rules that one IP per account so if you use some VPN to resolve the issue and later your account maybe go through verification or even can be terminated if someone from the IP you used earlier accessed the site.
Exclusive or not, it is still going to be bad idea to use VPN. I think somewhere I have read they do allow it but it has to be white listed IP and most importantly the country should be fine with gambling sites. Otherwise the player is doomed for sure. There is no going back if they have deposits, they wagered money and won it but in the later times site owners found out that it’s not legal IP or not acceptable Country then it’s gone, everything they earned or had on it will be blocked anyways.
I am not sure why peeps tend to take such high risks with their money? There are always options and we are anyways anonymous on these sites unless and until someone know your complete profile associated with XYZ username.
