Social Media Hygiene: What Not to Share Online

Conceptual image of financial scam with US dollars on yellow paper and word 'scam' visible.

Social media is where we connect, share, and express ourselves. But every post, like, and selfie is a data point — and sometimes, a risk. Oversharing can expose you to scams, identity theft, stalking, or professional consequences.

Social media hygiene means knowing what to share — and what to keep private.

Why It Matters?

Cybercriminals, data brokers, advertisers, and even strangers can gather a detailed profile of you from your social media activity. This info can be used for:

  • Phishing and impersonation
  • Guessing passwords or security questions
  • Social engineering scams
  • Job application screening
  • Location tracking and stalking

The line between personal and public is blurrier than ever.

Information You Should Avoid Sharing

🆔 Personally Identifiable Information (PII)

  • Full name, address, phone number
  • Date of birth
  • Passport or ID numbers
  • Email addresses used for logins

🧠 Clues for Password Recovery Questions

  • Mother’s maiden name
  • Pet’s name
  • First school, first car, favorite color
  • Birthplace or anniversary dates

🗺️ Live Location or Travel Plans

  • “At the airport heading to Rome!”
  • Check-ins, geotagged stories, or photos showing your address
  • Posts about being home alone or away for long periods

💳 Financial or Workplace Details

  • Paychecks or new job contracts
  • Credit cards, tax documents, or salary screenshots
  • Internal company info, even casually

👶 Children’s Photos and Info

  • Full names, schools, or birthdays
  • Unblurred faces in public posts
  • Routine schedules

🔐 Remember: What feels “private” might still be publicly accessible depending on your privacy settings.

Best Practices for Healthier Sharing

Set your profiles to private – especially on platforms like Instagram, Facebook, TikTok
Limit who can see your posts and stories (use Close Friends or private lists)
Disable location tagging by default
Avoid accepting friend requests from people you don’t know
Don’t post in real time – delay vacation or event photos until you’re home
Google yourself periodically to see what’s publicly visible

What About Professional Networks? (e.g., LinkedIn)

Even on business platforms:

  • Avoid listing your full work schedule or internal projects
  • Be mindful of oversharing career frustrations or layoffs
  • Don’t accept connection requests blindly — some fake recruiters harvest info
