LinkedGuard από Alice Sn0w

LinkedGuard highlights unsolicited messages in your LinkedIn inbox so you can ignore them at a glance - no more wasted time on recruiter copy-paste, crypto scams, MLM pitches, or "quick 15-min call" cold outreach.

What it does

When someone sends you a first message containing words from any enabled category, LinkedGuard:

• Highlights the sender's name in red, directly in your conversation list
• Adds a small ⚠ badge with a tooltip showing which list and which keyword triggered the flag
• Outlines the sender's avatar in red

That's it. Nothing is archived, nothing is deleted, no message is rewritten. You stay in control.

14 built-in categories

• Recruitment Spam
• Crypto & Financial Scams
• MLM / Network Marketing
• AI & Prospection Pitches
• Marketing Agency Pitches
• SEO & Backlinks
• Coaching & Mentorship Pitches
• Course & Training Sales
• Outsourcing & Offshore Dev
• SaaS Cold Outreach
• Phishing & Account Threats
• Investment Opportunities
• Generic Spam (disabled by default)
• Romance / Bot Greetings (disabled by default)

Around 180 keywords ship by default. You can toggle any list, edit its keywords, or create your own custom lists from the options page.

Privacy

LinkedGuard runs entirely in your browser. Nothing ever leaves your device:

• No analytics, no telemetry, no remote logging
• No fetch to any server outside linkedin.com
• Settings are stored only in your browser's local storage (with optional Firefox Sync)
• Activity log keeps the last 50 events, locally only

Permissions explained

• storage - saves your enabled lists, custom keywords and activity log locally
• tabs - opens the options page on the right tab when you click "Settings" or "Activity log" in the popup
• https://www.linkedin.com/* - the only site this extension is allowed to read or modify
