LinkedIn Spam Blocker

About

LinkedIn's feed is full of engagement-bait posts: "Comment CLAUDE and I'll send you the template", "Reply PROMPTS for the PDF", "Type SKILL and I'll DM you the checklist", and so on.

LinkedIn Spam Blocker automatically hides those posts from your own browser, so your feed stays focused on real professional content instead of comment-farming.

Why this exists

LinkedIn's reporting flow often leaves engagement-bait spam untouched, while reach-based incentives reward posts that generate empty comments. This extension gives you a local, private way to clean up your own feed without waiting for platform enforcement.

How it works

The extension scans supported LinkedIn pages for common engagement-bait patterns. When a post matches, it is hidden and replaced with a small placeholder. You can restore any post with "Show" or mark it as "Not spam" if it was incorrectly blocked.

Everything happens locally in your browser.

No analytics.
No telemetry.
No external APIs.
No remote blocklists.
No network requests.
No LinkedIn account data collection.

Privacy

LinkedIn Spam Blocker is designed to be local-first and privacy-friendly. It stores only extension settings and user-created preferences in browser storage, such as custom phrases, enabled languages, snooze state, block counts, whitelist entries, and false-positive signatures.

The extension makes zero network requests and does not transmit browsing data, LinkedIn content, or personal information anywhere.
