That for me is no grounds what so ever to block a players account and refuse a customers winnings.
So if I go to my cousins for the night, who also has a VS account, log in to my account and play will they reject my winnings too? I bet they will be all to happy to keep any losses
If the player didn't take any bonus I don't see the problem.
If the player can prove his identity and confirm he isn't the self excluded player what's the issue with using your account at a friends without a bonus? There is no way a player can exploit Videoslots or abuse a bonus if they haven't taken any. On the other hand a casino can exploit this "One IP address" situation and refuse winnings?
Be interesting to see what happens here.
But that's not what happened.
If you had gone to your cousins, who had Self Excluded from VS. Then decided to open an account for yourself at his, it paints a very different picture.
The OP could of gone on chat, to see if there could be any possible issues.
