If ASICSRUS ever made any claims and provided the reasoning behind his claims, we could easily argue against him.

But he says things like "you cheat by tracking IP addresses so expert dice players lose more" or "dice rolls depend on the amount staked" without providing any evidence.  You can't argue with stupid.

His posts are effectively content-free and are best ignored.

If he is the only source you have that math (the tech behind provable fairness) cheats, then that's a pretty sad state of affairs.

All the provably fair sites publish information about how the system works.  If you can find a flaw in it please do bring it out into the open.  The site operators all want to offer unquestionably fair games.  Keeping an average of 1% of turnover is plenty.  There's really no need to cheat the players.  You should try it some time.
