title: What does "respect the API" mean?
body: <p>On some websites that provide API service, they always mention that "Respect their API". I think when a website provide their API, they allow users to use them in a convenient way. We cannot really change the code or the output that we retrieve from the API. </p>
  
  <p>I'm just wondering what do we need to do to actually "respect their API" and what kinds of action are counted toward "disrespect their API"?</p>
