Default MediaWiki installation doesn’t provides you any feature to delete multiple pages at once. And no matter how many protections are active, spamming will always be present to a certain level unless you are running a completely private wiki.
Bot flood is the most common attack that happens on most wiki websites. In this attack, one or more vandals may attempt to run bots that can edit, move and create new pages at a very high speed and upload unwelcome versions of images.
As said by MediaWiki developers, “This is the most frequent kind of vandalism on most wikis and usually done for spam purpose.” We have already discussed about enabling ReCAPTCHA on MediaWiki in order to minimize such type of spams.
Now today in this lesson you will learn about deleting spam and unwanted pages in bulk on your MediaWiki installation.
