A fairly detailed (if not super easy to use) place to start is http://www.mediawiki.org/wiki/Anti-spam_features, which points to various extensions that can help out.
For a popular site, you'll need a holistic strategy for dealing with spam, which will include a few different tools, possibly something like: * Make your site less desirable for link spam, e.g. by setting $wgNoFollowLinks=true * Prevent bots with captchas (ConfirmEdit) and SimpleAntiSpam * Detect and block bad edits with AbuseFilter and SpamBlacklist * Monitor frequently, and be ready to cleanup with Nuke

Hi Markus!
I recommend you to use QuestyCaptcha to dissallow the bots to register and also use $wgAutoConfirmAge = 3600*24;

Liebe MW-Spezialisten,
Wir haben tausende Benutzeracounts von Spammern: http://wiki.openseamap.org/**wiki/Spezial:Benutzerhttp://wiki.openseamap.org/wiki/Spezial:Benutzer
Wie kann ich diese löschen? Eine "White list" von "guten" Benutzern ist vorhanden.
Gibt es da einen Bot?
Danke, Markus
