Rigged
Online poker is for the most part pretty above board, incidents like this are the exception not the norm. Your sarcastic comments and bullshit spouting are unwarranted, the random number generators used are vetted by respected 3rd party software houses and the most (if not all) of them use Intel hardware RNG to seed the shuffle. Those who cry about online poker being rigged are usually those who play poorly and are unable to psychologically deal with the stress of taking a few bad beats. The bad press generated by this sort of thing is not good for business for the site so it's in their interest to keep the games as fair and above board as possible.
You are at risk from players colluding against you, but then their is a risk of this playing live bricks and mortar as well... If you suspect something is not right you can report the incident to customer support though and they will analyze the incident.
You may also be at risk from automated bots depending on what game you play and what your skill level is, the AI is not yet at a stage where it is unbeatable though and the sites actively work to detect these things and deny the bots.
I have been playing for a while now both online and live and I use software to analyze my statistics and play, once you start to get a large enough sample you can start to see the results converging to around where they should be according to the mathematics of statistics/probability - that in itself is enough to prove that the software is in no way rigged.
