Lack of interest Discouraged user option


I would very much like to see an option to make a discouraged users' posts invisible to all non-admin users, similar to how the Tachy goes to Coventry option in vB worked.

I realize I could easily delete all of their posts and ban them, but the reason I need this option is that my board is primarily for customers. I do not want to offend a paying customer by banning them or moderating their posts when I could just make them invisible to everyone else and achieve the real goal, which is to just keep the board simple and targeted to software support.
