disclaimer : I havent used it since I am on linux. What about non-data related vandalism? Like someone painting the whole thing in pink? You start it one day and its blue, the next day its pink and the third day the "bold" button in some text editor application actually does italics?

Repeated vandalism is banned. Other conflicts are solved like on Wikipedia, where moderators step in if no consensus is found.

Furthermore, people are encouraged to add new features and create alternatives instead of modifying the existing classes, so that the popularity-based mechanisms do the job. For example, the "Filters" menu of the "Image Editor" is automatically populated with all the classes that inherit from the IFilter interface, sorted by popularity.
