Pavlo87's best case example was this comment (quoted above).
Look at the player tables. The #2 rated player has 0 losses on his record. That looks pretty impressive (and it is), and that player might even be motivated by that record, to play tight games and keep mistakes to a minimum, to preserve his perfect record (or he may not care about it at all--I wouldn't know). But that player will probably never play a non-rated game against a newer player in order to teach him something, like an opening, or a demonstration of a blunder, or how to mate in an endgame. So, that player will do one of three things, all of which are disadvantageous to this site and its players:
1. Create a 2nd account, in violation of the site policies.
2. NEVER use non-rated games for teaching purposes or other fun things like playing at a disadvantage.
3. Go to another site to do those things.
There is another strong player on this site who recently offered to play dozens of K-B-N vs. K endgames in order to teach others. What a great offer to teach others! He probably has tons of losses on his record because his helpfulness. If someone were to analyze his overall record without taking a lot of extra time to search through all of his games, move by move, that person would get an inaccurate picture of that player's strength. And isn't that one of the major purposes, if not the only significant purpose, of listing players' W-L-D records?
