This seems very strange but the post I've made here https://bitcointalk.org/index.php?topic=5045277.msg49125605#msg49125605 was about a site without scam

and here https://bitcointalk.org/index.php?topic=5045277.msg48004767#msg48004767 this guy seems to have proven this site uses different hashes and scam their users.

I'm not saying they are not scamming since they change hases, I was talking only about the variance in a not cheating probably fair game.
