The author of the website? Maybe he/she is just tired to respond to that question so many times?

In the other side, there's people that unfortunately don't know how to formulate a question and, most important, how to contextualize it. Education is the base, and we cannot expect everyone to have the same experience/capabilities managing languages, that's why it is on us to read between the lines, put our self in other people shoes and try to provide the most useful answer based in our knowledge...

You'd need to have a lot of empathy (and knowledge about the topic) to understand where that person is coming from and respond to such an ask-to-ask

And yes, agree @JesseJames Those 10$ could have been better invested.
