Preventing MediaWiki spam

gistfile1.php

// Garbee suggests the following settings in LocalSettings.php to help prevent bot spam:

// Number of edits an account requires before it is autoconfirmed
// http://www.mediawiki.org/wiki/Manual:$wgAutoConfirmCount
$wgAutoConfirmCount = 1;

// Number of seconds an account is required to age before it's given the implicit 'autoconfirmed' group membership.
// Note that the user must pass $wgAutoConfirmAge and $wgAutoConfirmCount to become a member of that group.
// http://www.mediawiki.org/wiki/Manual:$wgAutoConfirmAge
$wgAutoConfirmAge = 86400;   // one day

// Only allow autoconfirmed users to create new pages
$wgGroupPermissions['*']['createpage'] = false;
$wgGroupPermissions['user']['createpage'] = false;
$wgGroupPermissions['autoconfirmed' ]['createpage'] = true;
