It seems to be working along the principles of Denunciation, which is the theory behind shaming penalties. Shaming penalties work by expressing the community's moral condemnation of an act (in this case, noob farming), which instills a sense of shame in the offender and lowers his or her social status.
The problem with this theory in this particular situation is twofold.
1. The larger part of the Conquer Club community that goes to the forums will have seen that noob farming is going on, and will know about who has been "guilty" of the act. I would think it is hard to hear about noob farming in the forums, and not also hear who are the ones doing it.
Those people who do not go to the forums will not be affected by this at all. A noob farmer generally plays either very low ranks (in the individual case of JOHNNYROCKET24), or new recruits. Seeing as those people who do not go to the forums would probably not go around looking into people's profiles, only those who the farmers are playing would see the statistics and find something new (the rest of us know who is farming).
Not only do they generally not have access to the people's profiles, but those who do not go to the forums, will have little or no idea about what noob farming is, and I doubt they will care that much when they find out either.
So, let us consider the average new recruit that has a game joined by a farmer, seeing as that is the only type of person who will have access to the person's profile and may potentially care. As we can see by looking into any farmer's games played, only a very small portion of new recruits actually stay at the site long enough to complete even 5 games. This shows a rate of apathy, or dislike for the site. Few people choose to stay here after the first few games, as we can see by the several hundred thousand members of the site compared to the less than 20 thousand that are active. So in effect, the person who will see this statistic and learn about the player's game history will quit the site anyways.
2. If shaming penalties work by instilling a sense of shame and lowering the offender's social status, they can only be effective with those who care about the loss of social status and have some status to lose.
So, the question needs to be asked, how does one earn a status in Conquer Club? The answer, whatever that may be, is not by farming. A typical farmer is still well known in Conquer Club for that fact, but I have not seen them being given much respect or what you might call a "status" for some reason.
Therefore, since there is no status to lose. The whole theory of a shaming penalty will not work.
You might say that they do hold a status because of their high ranks, and I will agree. However, looking over the suggestion, I do not see anything that would take away their rank. If you still think that the shame by their average rank of opponent statistic will remove this "status" in the community, I suggest re-reading the first part of this post.
Now, it would be wonderful if someone actually took the time to read that.
