Are you geoblocked and have to use a VPN to get in? If you are goeblocked then it's your fault. If not you are getting scammed.
you might wanna read upon his post further. He literally said that he once was able to withdraw money form vave.com until he tried one day to do so and was disallowed, he got hit with a new change in their terms agreement that specifically bars russians from playing in their site. Such a change was weird and so they contacted him, under which they compensated the guy for the trouble with some extra as well. This is clear admission of guilt and a massive misplay on vave's part. Not in any way whatsoever the gambler's fault. He's borderline scammed if not for the fact that they paid him back his winnings and extra bonus for the trouble. which reinforces the fact that these gambling sites and casinos should always inform their players of changes like these.
