I quoted directly from a Wikipedia policy page and your reponse is a quote from a quibble between two other editors.
Care to address the substance of the policy I cited?
Yes.
A. "Attribute all quotations and any material challenged or likely to be challenged to a reliable, published source using an inline citation. [...]" Why is it likely to be challenged that chess.com is an internet chess server? Anybody with any common sense would go to chess.com and see that it is an internet chess server.
B. The objections you raise would perhaps apply to a full article on chess.com, but they do not apply to its inclusion in a list of internet chess servers.
C. If everything on wikipedia had to be sourced the way you are claiming, as an example, every song listed on every album mentioned in every music article would need such a citation from a book or article. I'm sure there are many other similar examples.
Your argument is foolish.
This all is a big tempest in a teapot by some web sociopath who has nothing better to do than pester Chess.com and Wikipedia about nonsense while claiming great injustices and a string of horrible and incomprehensible abuse aimed at his poor little self.
This troll has made several reincarnations here with the exclusive purpose being to raise nonsense issues about inflated misbehavior toward the spiders that exist solely in his skull.
I say the troll should be ignored.
From what I've seen this seem to be an excellent summary.
