[MediaWiki] How to roll back all user edits at once? (+ suggest good admin/anti-spam plugins)

Question

CMS

Good afternoon.

One new project is currently using MediaWiki. The engine is new to me, so some questions arise.

1. How to roll back all the user's edits in one action?
That is, there is a SpamBot user who managed to spoil a dozen pages. Rolling back changes on each page is somehow sad, I would like to delete all user edits at once.

2. What add-ons that make administration/fighting spam easier can you recommend?

Answer 1

And at the same time, how to prevent anonymous users from creating pages? In the "default" settings, you can disable only anonymous editing.

Answer 2

Answer 3

If the wiki portal is filled from under one address, then it is most reliable to enter in the root index.php a ban on editing from other addresses, except for this IP. The easiest way to clean up spam is in phpmyadmin.

if($_SERVER["REMOTE_ADDR"] != 'X.X.X.X' and isset($_REQUEST['action'])){
exit('<h1>Запрещено</h1>');
}

Then you can remove unnecessary links and authorization in the /skins/MonoBook.php template (choose your design), indicate before prohibited blocks

if(empty($_SESSION['wsUserID'])) return true;

Unauthorized users will not see these blocks, and since we have prohibited authorization and editing, no one except the admin will see special pages, etc.
I struggled with spam for a long time, now silence.
