The Thread of Shame was the rather informal name for it.
What it's basically meant to do is to cover the reasons behind formal warnings. Not the discussions, those will and should remain private, but if a user is banned we should have a place where other people can see what they were banned for. The Global mods will already know we do this internally already. There are a lot of posts on the global mod board saying "This user was monkeyed for a week for his actions on this thread" so the only change is to make an external version. But when someone like High Max gets banned for the straw that broke the camel's back, we can point at the Thread of Shame and say "Here's all the rest of the straw, here's a long list of examples of you making this forum a worse place to visit. That's why you're banned."
