"Inside info" is obtaining and using insider non-public information such as getting it on the down-low from someone working for Best Buy that there was a bug in the app, and then acting upon it. Nothing happened here except that some very smart and/or observant people noticed when they saw the ticker going up like crazy at the same time every day, and put 2 and 2 together.
If one wants to relate this to the "real" (i.e. non-contesting) world, the first example would be like insider trading and stock manipulation (both highly illegal), while the second example would be like someone performing technical analysis on a stock based on observations of public behaviour (e.g. the "Gifts Awarded" counter on the main contest page), and basing their buy and sell decisions on the results of that analysis (totally legit).
So is Roger suggesting that something illegal took place? If so, I hope that he has information to back that up, otherwise it might be construed as slander.
