Reddit Automation Skill

Automate Reddit using CamoFox CLI anti-detection browser. All workflows verified on 2026-03-04 with zero CAPTCHAs triggered across 50+ operations.

1. Prerequisites

• CamoFox browser running: camofox server status
• A saved Reddit session (see Section 2)
• Install: npm install -g camofox-browser

2. Authentication

Reddit login uses reCAPTCHA Enterprise — automated credential entry is blocked. Use session-based auth:

First time — login manually in CamoFox, then save:

camofox session save "reddit-session" --user reddit

Subsequent times — restore saved session:

camofox open https://www.reddit.com --user reddit
camofox session load "reddit-session" --user reddit
camofox navigate https://www.reddit.com [tabId]
camofox snapshot [tabId]

Verify: username visible in snapshot confirms login.

Store credentials for reference:

camofox auth save reddit-main --url https://www.reddit.com --notes "Reddit account"

3. Browse Feed

camofox open https://www.reddit.com --user reddit
camofox session load "reddit-session" --user reddit
camofox navigate https://www.reddit.com [tabId]
camofox snapshot [tabId]
camofox scroll down [tabId] --amount 500
camofox snapshot [tabId]
camofox get-links [tabId]

4. Browse Subreddit

camofox navigate https://old.reddit.com/r/test [tabId]
camofox snapshot [tabId]
camofox click [eN] [tabId]
camofox snapshot [tabId]

Old Reddit has simpler HTML structure — easier to parse post listings.

5. Comment on Post (Old Reddit)

IMPORTANT: Use eval to fill textarea — standard type causes 500 errors on old Reddit.

camofox navigate https://old.reddit.com/r/test/comments/POST_ID/ [tabId]
camofox snapshot [tabId]
camofox eval "const ta = document.querySelector('.usertext-edit textarea'); ta.value = 'Your comment'; ta.dispatchEvent(new Event('input', {bubbles: true})); ta.dispatchEvent(new Event('change', {bubbles: true}));" [tabId]
camofox snapshot [tabId]
camofox click [eN] [tabId]
camofox snapshot [tabId]

Why eval? Reddit's old textarea causes Internal Server Error when filled via browser automation type. Setting textarea.value via JavaScript works reliably.

6. Create Post (New Reddit)

IMPORTANT: Use www.reddit.com — old Reddit has visible reCAPTCHA that blocks posting.

camofox navigate "https://www.reddit.com/r/test/submit?type=TEXT" [tabId]
camofox snapshot [tabId]
camofox type [eN] "Your Post Title" [tabId]
camofox snapshot [tabId]
camofox type [eN] "Post content with markdown." [tabId]
camofox snapshot [tabId]
camofox click [eN] [tabId]
camofox wait navigation [tabId] --timeout 5000
camofox snapshot [tabId]

7. Reply to Comment (Old Reddit)

camofox navigate https://old.reddit.com/r/test/comments/POST_ID/ [tabId]
camofox snapshot [tabId]
camofox click [eN] [tabId]
camofox snapshot [tabId]
camofox eval "const tas = document.querySelectorAll('.usertext-edit textarea'); const rb = Array.from(tas).find(t => t.offsetParent !== null && t.value === ''); if (rb) { rb.value = 'Your reply'; rb.dispatchEvent(new Event('input', {bubbles: true})); rb.dispatchEvent(new Event('change', {bubbles: true})); }" [tabId]
camofox snapshot [tabId]
camofox click [eN] [tabId]
camofox snapshot [tabId]

8. Upvote / Downvote

camofox snapshot [tabId]
camofox click [eN] [tabId]

Vote buttons appear as arrow icon refs in the snapshot.

9. Session Management

camofox session save "reddit-session" --user reddit
camofox session load "reddit-session" --user reddit
camofox session list
camofox session delete "reddit-session"

10. Rate Limiting

• Wait 2+ minutes between comments/replies
• Wait 10+ minutes between posts for new/low-karma accounts
• Add delays: camofox wait networkidle [tabId] --timeout 3000
• Higher karma accounts have relaxed limits

11. Anti-Detection

• CamoFox anti-detection fully effective on Reddit (0 CAPTCHAs in 50+ operations)
• Reddit serves ads to CamoFox = treats as real user
• Use consistent userId ("reddit") across sessions
• Do NOT clear cookies between actions
• No special proxy or fingerprint settings needed

12. Platform Selection

13. Troubleshooting

14. Complete Example

#!/bin/bash
USER="reddit"
SESSION="reddit-session"

TAB=$(camofox open https://www.reddit.com --user $USER --format json | jq -r '.tabId')
camofox session load $SESSION --user $USER

camofox navigate https://old.reddit.com/r/test $TAB
camofox snapshot $TAB

camofox eval "const ta = document.querySelector('.usertext-edit textarea'); ta.value = 'Automated via CamoFox CLI'; ta.dispatchEvent(new Event('input', {bubbles: true})); ta.dispatchEvent(new Event('change', {bubbles: true}));" $TAB

camofox session save $SESSION --user $USER
camofox close --user $USER
