How do I automate the process of finding Reddit threads with no comments?

Finding Reddit threads with no comments can be automated by using a targeted search operator on Reddit or by querying external data sources (like Pushshift) and scheduling periodic checks. The core approach is to continuously fetch new submissions that match the “no comments” condition and store or act on them.

Quick, practical approach overview

• Use Reddit’s search operators to filter for posts with zero comments.
• Combine with a time window to capture fresh threads.
• Schedule a small script to run at intervals and log results.
• Optionally enrich with Pushshift for more robust filtering and historical data.
• Use alerts or a simple dashboard to monitor new results.

Option A: Reddit search operators (simple and fast)

What you’ll need

• A basic script or manual checks using Reddit’s web interface.
• A small HTTP client (Python requests, Node fetch, etc.).

Steps

1. Identify a subreddit or scope (e.g., r/technology or site-wide).
2. Use the search query with the no-comments condition, such as: subreddit:YOUR_SUBREDDIT comments:0 or site-wide: comments:0 for the entire Reddit.
3. Filter by time to focus on new posts (e.g., past 24 hours or today).
4. Parse the results to extract post IDs, titles, authors, and timestamps.
5. Store results locally or in a lightweight database for retrieval.

Pros

• Simple setup.
• No API key required for basic searches.

Cons / Pitfalls

• Search results may be limited or inconsistent.
• Rate limits on automated queries.
• Not ideal for historical or bulk data.

Option B: Pushshift API for robust automation

What you’ll need

• Access to the Pushshift API (public endpoint for submissions).
• A small script to query and process JSON data.

Steps

1. Define filters: subreddit, after, and num_comments equals 0.
2. Form a query like: submissions?subreddit=YOUR_SUBREDDIT&after=24h&size=500&num_comments=0
3. Run the query on a schedule (cron, serverless, or a small daemon).
4. Normalize fields: post_id, title, author, created_utc, url.
5. Store results and optionally set up alerts for new entries.

Pros

• More reliable across time and subreddits.
• Easier to paginate and accumulate data.

Cons / Pitfalls

• Pushshift may have occasional delays or API changes.
• Requires handling rate limits and data normalization.

Option C: Automated workflow with code (Python example outline)

Core components

• A scheduler (cron or APScheduler).
• A fetcher (Reddit search operator or Pushshift API).
• A small database (SQLite) or a CSV for logging.
• An alert mechanism (optional): email, webhook, or chat.

Basic workflow

1. Compute the time window for new posts (e.g., last 6 hours).
2. Query Reddit or Pushshift for submissions with 0 comments within that window.
3. Extract: id, title, author, subreddit, created_utc, url.
4. Append to the store and deduplicate by post_id.
5. Trigger alerts or compile a daily digest.

Example actions

• Create a Python script that uses requests to call Pushshift, filters for num_comments=0, and writes to SQLite.
• Schedule it with cron: run every 4 hours.
• Use a lightweight frontend or CSV export for quick checks.

Best practices and pitfalls to avoid

• Timezone handling: store timestamps in UTC and convert only for display.
• Deduplication: check post_id to avoid repeats across runs.
• API etiquette: respect rate limits; jitter schedules to avoid spikes.
• Subreddit scope: start with a few active subs before scaling.
• Data retention: decide how long to keep results (daily digest vs. archive).

Quick comparison of alternatives

• Reddit search operators: fastest for ad-hoc checks; best for small-scale needs.
• Pushshift API: most reliable for automation and bulk data; better for historical context.
• Custom script with Reddit API (OAuth) or PRAW: full control; requires handling authentication and rate limits.

Example checklist to implement

• [ ] Choose primary method (Reddit search, Pushshift, or combined).
• [ ] Define scope: subreddits, time window, 0 comments condition.
• [ ] Implement data fetcher (script or small app).
• [ ] Store results with deduplication.
• [ ] Schedule regular runs.
• [ ] Add alerting or a simple report.
• [ ] Periodically review results for relevance and accuracy.
• [ ] Monitor for API changes and adjust queries as needed.
