DisableBotMessageWalls removes the interface on the message walls of bot accounts, preventing users from posting. It is recommended to combine this with a greeting informing users about bots with a link to the bot operator's message wall. This can be done by creating a page with the bot's name in the "Message Wall Greeting" namespace. This will help reduce confusion for new users by informing them of the correct place to voice their questions or concerns about the function and use of the bot in question.
