Social Media Is Fun - But Watch Out for Your "Digital Tattoo"

Instagram, TikTok, X (formerly Twitter), Snapchat. Social media is a great way to connect with friends and share what you love. But here's the thing: once you post something online, it's almost impossible to completely erase it.

Someone might screenshot your post. Search engines might save a copy. Web archives might store it forever. Even after you hit "delete," the information can live on. This is called a "digital tattoo" - just like a real tattoo, it doesn't come off easily.

What's OK to Share - and What's Not

Before you post anything on social media, ask yourself: "Would I be OK if this was still online 10 years from now?"

Never share these

  • Your address, school name, or nearest station: Stalkers or strangers could figure out where you are
  • Photos in your school uniform: People can identify your school and wait for you on your way home
  • Photos with location data: Your phone's camera might embed GPS coordinates in every photo. Read about how the internet knows your location
  • Someone else's face (without permission): Posting a friend's photo without asking violates their privacy
  • Passwords or personal details: You'd be surprised how many people post things like "Just changed my password!"

OK with caution

  • Your creative work (drawings, music, photos) - as long as it doesn't reveal who you are or where you live
  • Your thoughts and opinions - but make sure future-you won't be embarrassed
  • Scenery photos - as long as they don't show your home or daily route

DMs from Strangers - 99% Are Suspicious

Sometimes a stranger sends you a message out of nowhere on social media. "You're so cute!" "Want to be a model?" "I know a way to make easy money." These are almost always scams or dangerous traps.

  • "I'll give you money" messages: These are scams to collect your personal info. Sharing your bank details could drag you into a crime
  • "Modeling/talent" offers: They'll ask for expensive sign-up fees or inappropriate photos
  • "Easy side job" pitches: Scams targeting young people are on the rise. "Make thousands from your phone" is always a lie
  • "I'm your age" claims: There's a good chance it's an adult pretending to be young. You can't verify anyone's age online

The right move with DMs from strangers is to ignore or block them. If something feels scary, talk to a parent or teacher right away. Knowing about social engineering tricks can help you spot these scams.

Check Your Privacy Settings

Most social media accounts share way more information than you think when left on default settings. Here are the settings you should check right now.

Setting Recommended Why
Account visibility Private Strangers can't see your posts
Location sharing Off Your posts won't reveal where you are
Who can DM you Followers only Blocks messages from strangers
Tagging permissions Require approval Nobody can tag you without your OK
Search engine visibility Off Your profile won't show up on Google

Cyberbullying - What to Do If You See It

Bullying on social media can be even worse than in-person bullying. It follows you 24/7, it can spread to a huge audience, and the evidence sticks around forever.

If it happens to you

  1. Take screenshots: Save the evidence. Even if the bully deletes their posts, you'll have proof
  2. Don't respond: Fighting back usually makes things worse. Ignoring is the best move
  3. Block and report: Use the platform's report feature
  4. Talk to an adult you trust: A parent, teacher, or school counselor. Don't try to handle it alone

If you see it happening to someone else

  • Don't "like" bullying posts. Don't share them either
  • Reach out to the person being bullied - even a simple "Are you OK?" in a DM helps
  • If it's serious, tell an adult

5 Rules for Using Social Media Safely

Social media can be an amazing tool that opens up your world. To enjoy it safely, keep these 5 rules in mind.

  1. Pause 10 seconds before posting: Ask yourself, "Would future-me be OK with this?"
  2. Keep personal info private: Your address, school name, and face should stay off public posts
  3. Ignore DMs from strangers: If it sounds too good to be true, it is
  4. Lock down your privacy settings: Private account + location off is the baseline
  5. Ask an adult for help when you need it: It's not embarrassing - it's smart. Getting help early prevents bigger problems
