Why you should only connect with people you trust on social media

Social media makes it easy to stay connected with friends, family, and coworkers. But it also opens the door to strangers, scammers, and cybercriminals who want access to your personal information. Even platforms that seem secure can expose more about you than you realize—and that’s why it’s so important to connect only with people you know and trust.

Let’s take a closer look at why this simple habit matters, how oversharing can put you at risk, and what you can do today to keep your social accounts safer.

The Hidden Risks of Connecting with Strangers

On the surface, accepting a new friend request or follow might feel harmless. Maybe the account looks friendly, or the profile seems familiar. But here’s the truth: many fake accounts are carefully crafted to seem legitimate.

Cybercriminals create fake profiles to:

  • Collect personal information
  • Guess passwords based on shared details
  • Launch phishing attacks
  • Spread malicious links
  • Gain access to your friends or workplace

Even if a social platform shows limited information at first glance, sharing just a little with the wrong person can open the door to much bigger problems.

Default Settings Aren’t Always on Your Side

Most social networking apps are designed for sharing—not privacy. By default, many platforms set your posts, photos, or status updates to “public,” meaning anyone on the internet can see them unless you change your settings.

This can expose:

  • Your location
  • Your travel plans
  • Your job or workplace
  • Photos of your home
  • Details about your family
  • Clues to password security questions

If your updates aren’t protected, you might be sharing far more publicly than you intended.

How to Lock Down Your Social Accounts

Good news: you can keep enjoying social media while protecting your privacy. Here’s how:

1. Connect Only With People You Know

If you don’t recognize the name or profile, don’t accept the request. It’s always safer to limit your online circle to trusted contacts.

2. Review Your Privacy Settings

Take a moment to check who can see your posts, photos, and personal details. Update your settings so only approved contacts—not the entire internet—can view them.

3. Limit What You Share Publicly

Avoid posting sensitive details like your address, travel dates, or workplace information. These small details can be used against you.

4. Watch Out for Impersonation Accounts

Scammers sometimes duplicate the accounts of real people. If something feels “off,” verify through another communication channel before engaging.

5. Keep Personal Info Out of Your Bio

Your bio should never include data that could be used to impersonate you or answer password recovery questions.

A Safer Social Media Experience Starts with Awareness

You don’t need to avoid social media to stay safe—you just need to use it wisely. By connecting only with people you trust and locking down your privacy settings, you protect yourself from scams, identity theft, and unwanted access to your personal life.

A few simple clicks can make a big difference. Your future self—and your online privacy—will thank you.
