I've blogged about wiki-ing anti-Patterns here before, and then when I went for a walk came up with several wiki-ing patterns and anti-patterns (which I cannot readily recall). But I decided to see if there was a previous effort. And indeed there is: Wiki Patterns - the meta-wiki for wiki-ing patterns.
It's not perfect. While browsing it, I noticed that they have a one big "Vandal" anti-pattern. However, I would separate Vandalism into several different anti-patterns instead of treating it collectively:
While they are all vandalism, they all require different ways of dealing with.
I may end up contributing to wikipatters.com as it is world-editable, but requires registration.
