OP, focus your attention on these casinos that are truly rigged:

bitcasino.io
4grinz.com
vegascasino.io
mbitcasino.com

They all use the coingaming.io platform and all of them besides vegascasino.io have topics here. primedice is provably fair and can be proven. i do not even play dice sites and i know that. go after the true scammers.

In my opinion.
