Features
What does it do?
Akismet helps keep your site free of spam by automatically scanning all posts from new users. Scanned posts that Akismet flags as spam are immediately removed from the site and added to a queue for review. Site staff can then review the posts to confirm spam, or restore if the posts are not spam. Akismet learns as staff confirm or restore spam posts, improving its spam detection and decreasing false positives.
Spam sucks, Fight it with Akismet
Akismet is a well known service that trains a Bayesian filter for detecting spam specific to your domain. Akismet is NOT free for commerical use, but can be for personal use. To use this plugin you will need an Akismet API key, you can get one here.
How it works
The plugin works by collecting info about a new post’s HTTP request. Every 10 minutes, a background job runs that looks for new posts. All new posts are sent to Akismet to determine if they are spam or not. If a post is deemed spam, it is deleted and placed in a moderator queue where staff can take action against it.
Configuration
For sites that are on our hosting, the Akismet plugin is pre-installed and enabled for you. For self-hosted sites, follow our Install a Plugin howto, using git clone https://github.com/discourse/discourse-akismet.git as the plugin command.
Once you’ve installed, add your akismet key under site settings by searching for akismet.
Alternatively, you can also add it using a DISCOURSE_AKISMET_API_KEY environment variable.
After enabling the plugin, you can find the moderator queue by visiting /review or selecting Review from the Hamburger menu.
From the review queue you can then filter for Akismet flags
| Action | Result |
|---|---|
| Confirm Spam | Confirms the post as spam, leaving it deleted, and tells Akismet that it was spam. |
| Not Spam | Akismet thought something was spam but it actually wasn’t. This undeletes the post and tells Akismet that it wasn’t spam. Akismet gets smarter so it hopefully won’t make the same mistake twice. |
| Ignore | Confirms the post as spam, leaving it deleted, but doesn’t notify Akismet. |
| Confirm Spam & Delete user | It will delete the user, their posts, topics and block their email and IP address. |
What data is sent to Akismet?
| Field Name | Discourse Value |
|---|---|
| Author | User’s Name |
| Author Email | User’s verified email (can be disabled with the akismet_transmit_email site setting) |
| Comment Type | “forum-post” |
| Content | Post’s raw column (including post’s topic title if first post) |
| Permalink | Link to topic |
| User IP | IP address of request |
| User Agent | User agent of request |
| Referrer | HTTP referrer of request |
Testing
Once you have the plugin installed, let’s do a quick test to make sure everything is working. Login as a non admin user and create a new topic and post. Use the following info:
title: Spam test - Will this plugin do what it says!
post: love vashikaran, love vashikaran specialist,919828891153 love vashikaran special black magic specialist hurry hurry love now
Now, go to /sidekiq/scheduler and find the CheckForSpamPosts jobs and trigger it. Now, as a staff member, view the moderator queue by going to /review or by using the Hamburger menu. You should see the post with some additional info about it.
