Wikipedia is taking new steps to help prevent “indirect” vandalism. Software has been created and is in use on the main page. It’s called “Cascading Protection” and it applies to local images and templates which are typical targets for vandalism. Andrew Garrett created this, and on his blog explains in a simplified way how it works:
Simply put, this automagically applies temporary full protection to any page included on a page protected or semi-protected with the “cascading bit”. Brion has so far protected the Main Page of en.wikipedia with this feature, which should eliminate main-page vandalism, except of images on commons; which could be uploaded by a bot, protected manually, or protected on commons.
Hopefully this new measure will put an end to the vandalism that Wikipedia has been a target of.
