Social media is an essential part of our daily lives. It connects us with friends, helps us share information, and even supports our businesses. But with its convenience comes risk: a single careless moment can lead to serious trouble.
This article summarizes five common SNS mistakes and provides practical solutions you can start using today.
1. Sending a Message to the Wrong Person
What Happens
This is one of the most common SNS disasters:
- Sending a complaint about a coworker directly to that coworker
- Posting a romantic message meant for your partner into a company group chat
- Revealing job‑hunting activities to your current boss
- Accidentally sharing a friend’s secret with the friend themselves
These mistakes can damage trust, relationships, and even your career.
Why It Happens
- Rushing and not checking the recipient
- Similar names in your contacts
- Auto‑suggest selecting the wrong person
- Handling multiple chats at once
- Fatigue or late‑night messaging
How to Fix It
- Try to delete the message immediately
- Apologize honestly
- Follow up directly (call or meet) if the mistake is serious
How to Prevent It
- Double‑check recipient, content, and attachments
- Add labels to contacts (e.g., “Tanaka – Work”)
- Save important messages as drafts
- Avoid messaging when tired
- Be extra careful in group chats
2. Accidentally Posting Private Information Publicly
What Happens
You intended to share something with friends only… but it was visible to the entire world.
Examples include:
- Photos revealing your home address
- Children’s school information
- Company secrets or unreleased product details
- Travel posts that show you’re away from home
- Documents with personal data in the background
Once posted publicly, information can spread instantly and permanently.
Why It Happens
- Misunderstanding privacy settings
- Default settings set to “public”
- Not checking the background of photos
- Location data automatically attached
- Underestimating how easily information can be traced
How to Fix It
- Delete the post immediately
- Ask friends to delete screenshots if they took any
- Review and adjust privacy settings
- Consult authorities if personal data may be misused
How to Prevent It
- Use a pre‑post checklist
- Keep location services off
- Set default visibility to “friends only”
- Review privacy settings regularly
- Post travel photos after returning home
- Blur backgrounds when needed
3. Posting Emotionally and Regretting It Later
What Happens
Anger, sadness, frustration, or alcohol can lead to impulsive posts:
- Criticizing someone publicly
- Complaining about your workplace
- Sharing emotional outbursts
- Posting while drunk
These posts can harm relationships, damage your reputation, or even lead to legal trouble.
Why It Happens
- SNS makes it too easy to post instantly
- Desire for sympathy or validation
- False sense of anonymity
- Impaired judgment when tired or drunk
- Using SNS as a stress outlet
How to Fix It
- Delete the post as soon as you calm down
- Apologize if you hurt someone
- Contact affected people directly
How to Prevent It
- Follow the “24‑hour rule”
- Write in drafts and review the next day
- Talk to a trusted friend instead of posting
- Ask yourself:
- Would I post this tomorrow?
- Would I show this to my boss or parents?
- Will I regret this in five years?
- Avoid SNS after drinking
- Find healthier stress‑relief methods

Common issues:
