If its rigged from the shuffle, I do not believe it's set to favor any player.
Good article. I would have liked it if there was an update on the algorithms currently in use. As for collusion or issues with the site that is always a risk and nothing to be surprised about. And easy to weed out I believe.
But the real question is, is the site truly doing a random shuffle? Which begs the question is anything truly random? Or are we just working off of incomplete data?
I remember when this first came up in the mid 2000's. Unfortunately I do not remember where I read it but the article expressed the idea of attempting a random shuffle. As per the article, the computers of the time were not capable of doing a truly random shuffle so they added a "fairness" algorithm. (Note - its been years since I read this so I apologize if I am misrepresenting here, this is to the best of my memory). It had to do with how many computations the high end processors could do at the time.
The following snippet is in response to someone asking about how to create an algorithm that would make a "truly random" number generator
"..A deterministic device will always produce the same output when given the same starting conditions and inputs - that is what it means to be deterministic. "Truly random number" is more of a philosophical viewpoint, as what does it mean to be random is the crux of the philosophical navel gazing (folks aren't even certain if atomic decay is random or follows some pattern we just can't figure out yet). A cryptographically secure random number generator is going to take some external source of entropy to make the device non-deterministic. .."

Note: the above issue does not bother me as I believe if it is valid, then all of us are dealing with the same thing so there is no edge assuming nobody cracks the algorithm.
