Video admitting that the site was down and that the owner will only give chips (peoples money) back to people he 'remembers' https://www.youtube.com/watch?v=wr9elG6AVHA

Seems to be an odd coincidence that the site had a bunch of corruptions and all the chips were lost.

Also the site is no doubt rigged as can be seen from this video, with a co-owner/admin admitting to scamming people with rings on when the clan was a staking for commission clan chat.

I'd say post that proof on their thread and discuss the issue with them
