Each act of applying a change to a Wiki can be seen as a "message".
One can use email spam filter (with some modifications, of course) as 
a first line of defense. If a proposed wiki change looks as spam to
"modified email spam filter" a user is confronted with a set of
challenges such as read letters from a distorted bitmap, answer silly
questions like Who invented Ruby?... etc.
Alternatively, spam filter decides to silently forward the change to
the Tarpit and also notify Wiki admin of the change if the probability
of this message to be a legitimate one is higher that certain
threshold.
