LinkedIn Spam Blocker by Carlos Ortega

LinkedIn Spam Blocker hides common engagement-bait posts that ask you to comment a keyword like "CLAUDE", "SKILL", or "PROMPTS" in exchange for a file, template, prompt pack, or access. It works entirely in your browser, with no analytics, no telemetry, no remote blocklists, and no network requests.

The extension includes built-in multilingual detection for English, Spanish, French, Portuguese, and German, plus custom phrase matching so you can adapt it to new spam patterns in your own feed. When a post is blocked, it is replaced with a small placeholder so you can restore it immediately if needed.

You can also mark a blocked post as "Not spam" to prevent that same text from being hidden again, snooze blocking for 30 minutes, whitelist authors you trust, and import or export your custom phrase list. It works across the LinkedIn feed, profiles, posts, company pages, groups, search, notifications, jobs, newsletters, and articles.

Everything is local to your browser. The extension does not report posts, contact LinkedIn, or send your browsing data anywhere.
