NoSpam

Prevent spam before it happens.

This module is currently able to enqueue IP addresses of your visitors. It automatically sends them, 15 at a time, as specified by the documentation of the API it uses, to the webservice of http://www.stopforumspam.com/ in cron.

The result it gets is then evaluated using configurable settings, such as frequency (amount of times a 'hit' is made) and confidence (how confident the webservice is this is a spammer). Whether it is a spammer or hammer, the result is stored/cached for a configurable amount of time in the database.

The IP addresses get automatically added to the blocklist if safe mode is disabled and they get auto-removed when the status has expired.

Planned features for now:

• Report spammers to the webservice
• From experience, the hook_cron is too slow
  • Implement own cron, e.g. run every 5 minutes, configurable
  • Send specifiable amount of requests per cron run

Configs:

• Safe mode - disable autoblocking/autounblocking
• n% chance to be enqueued
• Minimum frequency
• Minimum confidence
• Cache results for n months
