[pydotorg-www] Spam on Jython wiki

[Skip Montanaro]

The Jython wiki continues to get spammed, whereas the Python wiki seems not
to, certainly not anything like happens to the Jython wiki.  Is there some
setup difference between the two that we've not accounted for?

I recall that Martin added a feature to the Roundup instance a couple years
ago which prevented new users from posting for a short amount of time (just
a couple minutes as I recall).  Could we easily apply a similar check to our
MoinMoin instances?
