Here's an interesting fact: np links don't actually mean jack shit. Subreddits can detect that you're visiting from the np subdomain and display a message or otherwise alter their appearance, but that's by their choice. You can actually put other letters as a subdomain if you want. Like this:

Of course, if the admins don't like what you're doing they'll go after you, but not because of the np link.
