Amongst other things like the irrationality of a poker site to rig their software and the infinately large security measures to prevent it, it mentions human behavior.
I thought it was quite interesting because people do become suspicious if they aren't physically able to see what is causing cards to come the way that they do.
Here is a snippet from the article:
Reasons for this natural suspicion lie in the fact that the mechanism controlling the outcome of an event cannot physically be seen. Unlike in a live game, you are unable to see the cards being shuffled and cut.
