A wall of shame sounds amusing at first blush, but it would quickly become a source of a lot of negativity and unhappiness. Yes, developers need to be aware of bugs, and learn from mistakes, but intentional harassment seems a step too far. I know I've written thousands of bugs.

A friend that used to work at Apple once told me a story of their department having a big banner over the desk of the last person to broke the build. Eventually a frustrated recipient of the banner solved the problems causing it to be brittle in the first place, and as a result had the banner himself for months. A rather unexpected disincentive to solve the problem

I agree it can definitely turn counter-productive quickly. On the other hand, if not a wall of shame, I would like to know what happened if it was my code.
