Thread:Project:Support desk/Media Wiki is a spam machine unless it is set up properly./reply (5)

As for the spam filters, there are extensions, which are coming with MediaWiki by default and which you can configure as you like (SpamBlacklist, TitleBlacklist, ConfirmEdit or so). All you have to do is to configure them. It does not really make sense to activate them preconfiguredly in some way as then spammers would just adapt to that one preconfiguration, which would make it useless.

When you set up MediaWiki there is an option to make it an "open wiki", "closed wiki" and so on. These texts tell something about who can edit the wiki in each case. However, I do not know the exact texts right now. Maybe a recommendation at that place would make sense.
