This hyphothesis would appear to be invalidated by our expirence
removing spam from english Wikipedia. It is fairly common that a spam
site will vanish off google right after removing it from enwiki, far
too quickly for most of the mirrors to catch up.

For the few mirrors that we have a good enough relationship with to
send a live OAI feed to, we can probably suggest that they nofollow
externals coming in from Wikipedia.  It's doubtful that they'd have a
problem with doing this.

When it comes down to it though,  most of the mirrors that have
significant placement on the search engines are engaged in spamming
SEO behavior themselves.  If someone wants on one of those sites,
there are probably even easier methods than inserting their content in
wikipedia and waiting for it to be mirrored.

Only if someone can demonstrate some evidence that we are really good
about removing bad links once they go in, and that anyone gives a darn
if they get impact during the 24 hous their ill fated link survives.
