why are there two domains for the same content and yet treat users differently

You get treated exactly the same on all domains. It's the exact same code on all of them.

If you're asking why there are multiple domains? dunno.

What triggers this domain switching?

Following a bad link someone made in a post or in the CB, like the one you created in the parent post.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
