Mediawiki - Removendo Spam

O seguinte documentação funciona da seguinte forma:

grupos e permissões

• Crie as regras de restrições de edição e criando grupo no MediaWiki, adicionando em LocalSettings.php

$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['user']['edit'] = false;
$wgGroupPermissions['human']['edit'] = true;
$wgGroupPermissions['sysop']['edit'] = true;

adicionando usuário no grupo

• Adicionar os usuários humanos no grupo "human". Há duas formas de fazer, via interface administratica web do MediaWiki, indo emPáginas especiais > Gestão de privilégios de usuários > Localize o usuário > acrescente no grupo "human"

ou pela linha de comando no MySQL: <source lang="mysql"> INSERT INTO mw_user_groups ( ug_user, ug_group ) VALUES ( 3, "human"); </source>

queries de remoção

Depois um conjunto queries que identificará tudo criado por usuário que não está no grupo human e removerá esse conteúdo e depois os usuários.

As queries usados foram:
