Some sites are also certified by 3rd party sites like iTech Labs. For example, our site has the certificate accessible when you click on the Provably Fair logo. The certificate can also be clicked and sends you to their site confirming the certification

1) Your whole provably fair page is nonsense.
1) The
actual certification just says they evaluated the outcomes for statistical randomizes. That does not imply they can detect or certify that you're not cheating (as you claim). In fact, the certificate is more for the casino than the player. It (tries to) reassure the casino their outcomes are not-predictable, which means players couldn't take advantage of it. It gives zero assurances to players.
2) Who ever issued that certificate (itechlabs) are actually retarded, even for a retard standards. Their recommended algorithms are pretty much the worst algorithms you could possible use for a casino. I would assume someone who did CS101 would know better. If someone actually followed their advice, anyone who knows how you call the random number generator could pretty with a bit of elbow grease could reconstruct the state vector and predict future outcomes.
In fact, generating random numbers is really easy. Read from /dev/urandom and you're done. Or use a crypto rand from your favorite programming language, simple as that. Meanwhile they recommend the exact thing you should be avoiding..
3) Your site is not provably fair, you're asking us to trust you and/or the retarded company that issued a meaningless certificate.
