I wanted to cite a statistic on whether vandalism at Wikia is higher or lower than on Wikipedia, but couldn't find anything. Is anyone familiar with research that I may want to check out? I am drawing almost nothing for studies of Wikia, outside the recent paper by Aaron Shaw and Benjamin Mako Hill (CC-ed), which did not however focus on vandalism.
This is the closet article I know about it. It doesn't talk about "vandalism" per se but it does look at levels of reverts and compares them to levels in Wikipedia. I think it's actually pretty close to what you are looking for:
Kittur, Aniket, and Robert E. Kraut. “Beyond Wikipedia: Coordination and Conflict in Online Production Groups.” In Proceedings of the 2010 ACM Conference on Computer Supported Cooperative Work, 215–24. Savannah, Georgia, USA: ACM, 2010. doi:10.1145/1718918.1718959.
Wikia (the largest wiki farm?) appears to be drastically under-researched...
I agree with this completely! art of the reason that there is so much research about Wikipedia is that the WMF goes to incredible length to make things easy for researchers with providing datasets, etc. Basically everybody else, including Wikia, does less.
