A plugin that blocks spam and malicious visitors without captchas or moderation queues, using its own detection plus Stop Forum Spam and Project Honeypot reputation data. It can block IP addresses temporarily or permanently, and block whole countries, regions or cities. Settings can also be managed through a REST API. It suits sites facing persistent spam or abuse. The plugin is free, and optional enhanced protection uses a Zero Spam licence key.
