Fake players or predefining winners would work as well.

My point was simply that an online casino could seem completely legit even if you can compile audit logs of every players' hands at the table. Controlling the community cards is completely undetectable and more than enough to push larger pots, and therefore larger rakes.

It's not undetectable.

Most pots already hit maximum rake.

How would one detect it?

As far as I'm aware, you would have to know the full list of cards in the shuffled deck before the hand was played to know they didn't change the community cards.

Because it shows up in analysis of millions of hands.

The community cards are subject to the same frequencies as the hole cards.

(And you can see them more often, so they're actually easier to analyze)
