Extension:StopForumSpam/en

The StopForumSpam extension allows wikis to utilize and contribute data to stopforumspam.com. It features automatic IP blocking and an easy interface for administrators to submit data. Use of the IP blacklist requires that you use some kind of object caching; it won't work if you have set to CACHE_NONE. If neither APC or Memcached is an option, the simplest approach is to fallback to storing the object cache in your MySQL database. The following preset (in LocalSettings.php) will do that:

Configuration parameters

 * - location of an unzipped IP address blacklist

User rights

 * - allows users to bypass blacklisted IP blocks

AbuseFilter integration
When using the AbuseFilter, a variable named "sfs_blocked" is added. The value is false if the user is not a spammer, and true if they are a spammer.

IP blocking
You can download IP blacklists, and import them using the  script. StopForumSpam has several lists; we recommend using the "listed_ip_30_all" list. Once you choose the list you want, download and extract it to somewhere on your server, then point  in the LocalSettings.php file at it. We recommend setting up a nightly cron job to download and extract new versions of the list and subsequently running the updateBlacklist maintenance script.

If that IP tries to edit, or a user tries to edit through that IP address, they will be prevented from editing. To exempt a user from being blocked, give them the  user right.
