The classification of individuals according to lists of competition in any area, from intellectual models to video games, is called classism. And discrimination based on that classification is also called classism.
Regardless of whether or not this list was made with the objectivity of a Jew threatened by thirty Nazis (are you seriously putting Darklight behind me?), It is totally retrograde and above all shows a conceit that should be motive of shame more than pride from your part.
Probably the most childish characteristic of your list is not to erase the names of those who have asked you, first, because you show an ecpathic character (contrary to empathy) and, second, because you believe that the position that you or anyone who has voted this list is not mere prejudice. When a list is not based on mathematical criteria or objective minimums (empiric stuff), has the same quality that a shopping list has, insubstantial and arbitrary. To give you an idea, FIFA to make its games, relies on more than 5 million specific data to make the rankings of the players and is still considered a subjective and false list.
Asking a minimum of good sense, erase the name of whoever asks you and stop believing that a video game is a reason to believe yourself superior or discriminate against someone.
You can subjectively argue that some of the players have been unfairly rated and are being discriminated against because of personal or regimental relations with those whose opinions have been used in making the list, but the inherent subjectivity of the list itself makes it almost impossible to highlight an example of discrimination. As you correctly point out, it is an arbitrary and insubstantial list based on the given opinions of several players, something which is made worse by the absence of classifications or requirements for each tier. All that means is that, with that knowledge, you should be less concerned with the conclusions of the list, because you know that it is solely based on opinion and subject to arbitration and, surely, to some personal discrimination by the contributors as relating to certain individuals, the latter being something which you could not prove without a stricter classification system or a direct admission.
The continued inclusion of people who request to be removed is not evidence that Ciiges considers himself superior or in a position to discriminate against anyone. That's a leap of logic which doesn't connect. You might say he should respect the wishes of that person and remove them, which is fair, but the fact he doesn't is not necessarily evidence of a belief of superiority as it could just as well be evidence of, and I believe this to be case, his continued commitment to maintaining the list in its whole form. If too many players are purposefully removed then the list no longer displays a full picture and is at a loss for legitimacy. I think it's quite obvious that Ciiges wants to keep everyone on the list because he wants it to be considered a generally accurate picture of the scene relating to skill, not because he thinks he's superior and has the right to dictate everyone's skill level. Not that the last point even stands on its own either, since the ratings are the combined opinion of several players from different parts of the scene and do not represent Ciiges' personal view.
You should accept its subjectivity, which is unavoidable in quite literally any list that is not based on statistical data, and from that you can choose to take it as seriously as you like. I do agree that a more precise classification system would improve the list, especially if it was categorical, and having the opinions of many different people on a wide number of categories would surely improve the perceived accuracy of the list. That said, it's a lot of work for something which would only change players' ratings by a few decimal points.
