[Labs-l] Ensure your MediaWiki install is either locked-down or properly patrolled

[Ryan Lane]

We've had some issues with really bad vandalism on some public
instances that have MediaWiki installed in such a way that allows
anonymous editing.

If you are using MediaWiki and your instance has a public IP which
allows access to the outside world, then you must lock down your wiki,
or you must properly patrol it. When community members inform us of a
vandalised wiki that isn't being cleaned up, we'll be forced to
disable access to the wiki via the project's security groups.
