Wikipedia & Tor & vandalism patterns?

[Marc Abel]

I don't know the Wiki codebase at all.  I understand how pages can be
vandalized, and I seem to infer (from some comments) that some of this
vandalism is en masse.

I'm curious, whether the vandalism can be "localized" in terms of its
style.  Are we talking about one rogue programmer from _______ (anyplace
you might name), or are we talking about hundreds of individuals with
their own styles?

Would it be helpful to set up "test cells" in which Tor exit nodes can
appear to vandalize the Wikipedia, so that patterns can be studied for
circumvention?
