There isn't an easy way to remove message walls from a certain user. (I am not sure if there is a way) But as Tupka said, just make your bot's Message Wall Greeting extremely long, and stating that it will not respond to any messages. Put it in a bold font and color to make it very noticeable.

Hope this helped!
