does that make it ok?

  A market maker's job is to have orders sitting on the book to provide liquidity to the market.

    sure.. but does that mean it's ok if they stuff them with their own orders in a way nobody else can and that gives them guaranteed profit at the expense of others?

      It does. And exchanges and other venues are continually updating to prevent market micro-structure from being able to be easily exploited.
