What is the earliest someone detected a skipped nounce on a string of their bets? When was this "employee" (yeah right) hired?

The thing that I'm trying to wrap my head around is why didn't the site owner just steal undetectably by just knowing the server seeds? Is this just pure stupidity and boldness in trying to skim the profits? I'd love some more theories.

Last statement: Even if this story is 100% true (newsflash: it is not) the site owner is a complete idiot for letting a days old "employee" let code go live without checking the code. At BEST the site owner does not know how to run a business and is completely reckless. Another day in Bitcoin scam land.
