I would say a definite "yes" to the inherent ability of software options always existing for site owners and operators. It seems just a matter of control and greed that dictates the general usage and deployment of the optional factors built into the programs. From the auto chat monitors to the random number generators, it may be a matter of particulars to accomodate a sites agenda.
As far as the free rooms, they are certainly not indicative of the reality of a pay room by any means. While participation in a free area may allow you to see the patterns and graphics, it does not disclose a clue as to the possibility of a "same winner syndrome", house players, or attentive chat hosts. There is no possibility of losing money and little possibility of winning a game with a large volume of players. Some free rooms do not allow chat access to further inhibit your ability to investigate the ambience and mood of the site.
The player does not actively participate in making decisions that will affect a gaming venues outcome, such as when to play a specific game, how many cards to purchase, and in many cases, auto selection of cards is a programmed feature. You are more of a bystander than a "player". On top of this, it is an area where a site can bombard you with advertisements, promotional pop ups, and deposit bonus offers.
You win nothing....you lose nothing. Not a very exciting proposition for the real gambler, but does offer a looksee into selective operational style, the regulations and rules and a general visual format.
