My conclusions so far
- Based on (1A) through (5A), the issue is not script or malware related.
I don't think that's a safe conclusion. Just because your malware scanner doesn't detect the malware doesn't mean it's not there. None of them are perfect. And being on a Mac doesn't mean you're safe.
One of the biggest whales on Just-Dice (LiKaShing) once had exactly the same thing happen, and said it must be JD's fault: he was on a Mac and couldn't find any malware so it couldn't be malware to blame. I don't think that follows.
Why only problems come from PrimdeDice and why always people still playing there.
That's easy, all dice sites have "problems". At Just-Dice we had several users get their accounts compromised and have their funds withdrawn.
