Do you know of any cases where someone hit 10,000? confirmed, not edited. By the way, it's interesting that the site lasts so long and is constantly developing.
What do you mean by "confirmed, not edited"?
Check out this thread,
Big wins at FreeBitco.in. There are tons confirmed hits of 10,000. Like ,
this one, for rexample.
I hit 10,000 myself recently, but on free rolls, unfortunately, it was in the Multiply BTC game. But I did roll 9998 on free rolls some time ago and won $20 with that, plus $5 for reporting it in that thread I mentioned above.
