Redditard, Automated Reddit Commenting Bot

This program uses Selenium/Thirtyfour WebDriver and Ollama to automatically browse Reddit, generate human-esque comments using AI, and post them to various subreddits with 'natural' behaviour patterns. Your account will eventually get flagged and your IP will be banned, I NEITHER CARE NOR AM RESPONSIBLE FOR HOW YOU USE THIS PROGRAM. ALL ON YOU!

Features

• Logs into Reddit and navigates subreddits automatically
• Generates contextually relevant comments using local LLM (Ollama)
• Mimics human behavior (random scrolling, typing delays, pauses)
• Supports multiple subreddits with different sort modes
• Customizable AI prompt via configuration file
• Tracks commented posts to avoid duplicates
• Optional voting on other comments (high risk feature, you will get flagged quickly)
• Headless or visible browser modes
• Predefined reactions list as an alternative to Ollama

Requirements

• Rust & Cargo
• ChromeDriver running on port 9517
• Ollama installed and running
• Reddit account credentials (gross)

Compile

cargo build --release

Configuration Files

subreddits.toml

Define which subreddits to target and how to sort posts:

[[subreddits]]
name = "unixporn"
sort = "hot"
[[subreddits]]
name = "programming"
sort = "top"
timeframe = "day"
[[subreddits]]
name = "askreddit"
sort = "rising"

prompt.toml (Optional)

Customize the AI prompt used to generate comments. If not present, uses default prompt.

custom_prompt = """
You're browsing r/{{SUBREDDIT}} and just saw: {{TITLE}}{{BODY_CONTEXT}}
Write a quick 1-2 sentence reaction.
Just write the comment, nothing else:
"""

Available placeholders:

• {{SUBREDDIT}} - Subreddit name
• {{TITLE}} - Post title
• {{BODY_CONTEXT}} - Post content preview

reactions.txt (Optional)

A plain text file with one reaction per line. When provided via --reactions, Ollama is skipped entirely and the bot picks a random line from this file instead.

• Lines starting with # are treated as comments and ignored
• Blank lines are ignored

# General reactions
ngl this is actually pretty cool
tbh didn't expect that lol
fr though this is wild

# Hype
yoo no way
deadass did not see that coming

# Chill
solid
not bad at all
pretty neat tbh

Environment Variables

Set your Reddit credentials:

export REDDIT_USERNAME="username"
export REDDIT_PASSWORD="password"

This isn't safe.

Flags

Option	Description	Default
--model, -m	Ollama model name	deepseek-r1:latest
--headless, -H	Run browser in headless mode	false
--verbose, -v	Print detailed debug information	false
--min-interval, -i	Minimum seconds between comments	60
--max-interval, -x	Maximum seconds between comments	600
--upvote, -u	Enable voting on comments (HIGH RISK)	false
--reactions, -r	Path to predefined reactions file (disables Ollama)	none

Output Files

This program will output a lot of pointless files.

• posted.txt - Log of all commented posts with timestamps
• login_page.png - Screenshot of login page (if verbose)
• before_submit.png - Screenshot before submitting comment (if verbose)
• .reddit_bot_ack - First run acknowledgment flag
• .reddit_bot_upvote_ack - Upvote feature acknowledgment flag

Behaviour

• Randomly selects subreddit from config
• Checks up to 20 posts per subreddit visit
• Skips already commented posts
• Waits 60 to 600 seconds between comments
• Uses human-like typing (20-80ms per character)
• Random scrolling and pauses
• Rotates user agents for anonymity
• Optional comment voting (8.3% upvote, 14.3% downvote, 77.4% skip)

Troubleshooting

• ChromeDriver errors: Ensure ChromeDriver is running on port 9517
• Ollama fails: Verify Ollama service is running and model used is downloaded
• No posts found: Check subreddit names in subreddits.toml, else blame reddit updating This program isn't time proof. Reddit slightly changing its UI will break it. It's open-source so if you like it you can fix it yourself :)
