It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question, see the FAQ.
This is just an example, there are other members doing this too. Sometimes the comments contains just the link, sometimes a short quote.
That’s not helpful.
I disagree that it is inherently unhelpful to quote from the FAQ regarding why a question received a close-vote. In fact, it can be inherently helpful, especially since, IMX, the vast majority of the time, the OPs of such questions haven't actually bothered to read the FAQ before posting their questions.
I think comments should explain how this specific question could be improved. Telling someone (usually a new member) to read some site without any further hint is on the edge of being rude in my opinion....

The goal is simple: to keep Stack Exchange a welcoming, friendly place without lowering our standards. No, you may not ask “plz send me the code” questions, but if you do, we will explain to you, in a friendly and professional way, what you did wrong.
I think that quoting from the FAQ is "friendly and professional". (And if it isn't, then the FAQ itself may not be "friendly and professional" enough.)
For off-topic question close-votes, I always try to indicate the scope/topic of the question, to explain why the question isn't WordPress-related. For duplicate questions, I'll generally link the search query I used to find the original question for which the new question is a duplicate. But for "not a real question" close-votes, I may or may not elaborate. If I think the question can be salvaged, I'll ask clarifying questions without casting a close-vote. But if I don't think the question is easily salvageable, I'll generally close-vote, and quote from the FAQ.
Being friendly and welcoming does not mean that we absolve users of their responsibility to understand how SE sites work before asking questions. On a site such as WPSE, where so few community members can actually use a community moderation tool such as close-votes, and where such a high percentage of questions require community moderation (due to being poorly written, out-of-scope, duplicates, etc.) it is only prudent that we not facilitate users who don't read and understand the ground rules/workflow before submitting questions.
Obviously, we can debate where exactly the line should exist, and wherever the line should be we should always be friendly and welcoming. But IMHO quoting from the FAQ as explanation for a close-vote falls on the correct side of that line, wherever it is.
