I was recently looking up which countries were in the Congo Basin, and
the version of the article I found was this:
http://en.wikipedia.org/w/index.php?title=Congo_Basin&oldid=359085351
The list of countries is clearly missing.
It was removed with this edit:
http://en.wikipedia.org/w/index.php?title=Congo_Basin&diff=357222409&am…
That was 20 April 2010 (I've now restored the list).
Has anyone done a recent study to see how and why vandalism like that
is missed and how common it is for such things to be missed?
