well you don't have to worry about Lamabet, they are closing on Nov 1.

if it had been a 38 USD instead of 3800 USD amount they wouldn't have accused you of any multi accounting.

I think if we shake things up by making some premiums (and non premium contests) be random draws, each 50x+ is worth 5 entries and maximum of 50 entries per member per draw. 

Trying to claim back your winnings and deposits from the casino may not be an easy task because you won't be able to provide solid proof that you didn't create those duplicate accounts. The AGCCS Team would usually depend on whatever proofs the casino would provide to the team, which would definitely be not favourable to you. Nonetheless, you can try your luck by filing a complaint via AGCCS facility.

1xbet accused me of playing with multiple accounts. Without specifying which account or which ID. Then all my winnings along with my deposits were confiscated and my ID was permanently blocked. The total funds seized and not paid out is around 3800 USD.
