Reddit Automoderator Guide: Essential YAML-based Moderation Tools

• Automoderator is a built-in Reddit tool that uses custom rules, filters, and templates to automate moderation tasks.
• It helps remove spam, enforce content rules, and streamline tasks with YAML-based configuration.
• Learn how to get started, write your rules, and manage changes effectively.

Automoderator can be a game-changer for any growing subreddit. By automating repetitive moderation tasks, you can focus more on engaging with your community and less on manual content reviews. Whether you run a small community or a large one, using Automoderator effectively helps maintain content quality, ensures rule compliance, and saves precious time for moderators, as outlined in working with mods.

Incorrect rule setup can lead to unwanted removals or letting inappropriate content slip by, so getting it right is essential for a smooth-running community.

What is Automoderator?

Automoderator, often shortened to Automod, is a customizable bot built into Reddit. It uses rules you create to automatically carry out moderation tasks on new content.

This includes removing posts with banned keywords (see avoiding bans spam labels), sending modmail alerts, replying with helpful comments, and filtering out spam.

According to the Reddit Help Center, every subreddit has access to Automoderator.

Setting Up Automoderator

To start using Automoderator in your subreddit, access your community’s Automod configuration page via a wiki that requires both manage settings and manage wiki pages permissions.

Navigate to your Automod config page and click the create page button if it doesn’t exist.

Rules, Filters, and Templates

Automoderator operates on rules written in YAML. Each rule consists of a check and an action.

For example, a rule might remove posts containing banned words while filtering based on domain, comment length, or user karma.

Best Practices When Writing Rules

Keep it simple by starting with basic rules that enforce community guidelines.

Use comments and placeholders in your YAML to explain the rule purpose, and test your rules in a safe environment before going live, utilizing ab testing for reddit to verify performance.

Practical Examples

For spam and troll prevention, use rules to filter content from new accounts or those with low karma.

Set up automated replies for posts with formatting mistakes to guide new users, and configure modmail notifications for posts meeting specific conditions.

• Syntax Errors: YAML is sensitive to spacing and punctuation. Use spaces (not tabs) and maintain consistent indents to avoid rule failures.
• Overly Broad Rules: Rules that are too general can end up removing acceptable content. Test each rule extensively to ensure that it triggers only when necessary.
• Ignoring Version Control: Always use version history for your Automod config page. This practice allows you to quickly revert to a working configuration if new rules cause unintended removals or issues.
• Lack of Comments: Without comments, it becomes challenging for your mod team to understand the purpose behind each rule. Include clear descriptions for every rule added.

Now that you have a basic understanding of Automoderator and how to configure it for your subreddit, start by reviewing your community’s current rules. Identify recurring moderation tasks that can be automated. Experiment with these rules in a test environment and gradually introduce more complex configurations.
