Social media posts, photos, blogs, reviews, consultation text, file sharing.
Individual publishing is not limited to special announcements. The accumulation of everyday posts connects to the person, family, children, friends, workplace, and routine places.
This checklist is for pausing before posting.
The purpose is not to erase everything perfectly. The purpose is to find and reduce information that could cause trouble after publication before publishing.
First Things to Check
First, check direct personal information.
Look for names, faces, addresses, schools, workplaces, phone numbers, email addresses, IDs, notifications, shipping labels, and name tags.
Check item
Where to look
Name
Body text, image, name tag, document, screen notification
Face
Photo, video, reflection, group photo
Information close to an address
Background, shipping label, nearest station, place name
School or workplace
Uniform, company name, notice, email screen
Contact information
Email address, phone number, social media ID
If direct information appears, decide before publishing whether to delete it, blur it, crop it, or stop posting.
Are You Involving Family or Friends?
Individual posts easily involve people around you.
Even if you are comfortable publishing something, children, family, friends, and colleagues may not have consented.
Check item
Caution
Child's face
Becomes information that remains into the future
Uniforms or school events
School or region becomes known
Friend's face or name
The other person's consent is needed
Conversation screenshot
The other person's icon, name, and notifications remain
Workplace story
Colleagues or departments can be inferred
Anonymity is not only about yourself.
Check whose information your post exposes.
Check Photos and Videos
Photos and videos carry a lot of information.
Even if you hide faces, background, reflections, text, sound, location information, and post text can reveal information.
Check item
Point to look at
Background
Store names, station names, school, workplace, outside window
Reflection
Mirror, glass, smartphone screen, metal
Text
Name tag, document, notice, shipping label
Sound
Voice calling a name, station announcement, workplace sound
Metadata
GPS, capture date and time, device model, filename
Video carries more information than photos.
Even a few seconds of video can include background sound, screen notifications, reflections, and a movement route.
When checking, it is important not to judge only from the small preview on the posting screen.
Text and backgrounds that are not visible on a smartphone may be readable on a large PC screen. Enlarge the image and check the edges, reflections, outside the window, desk surface, and notification area.
Check order
Reason to look
Look at the whole image
Understand what is shown
Enlarge
Find small text and reflections
Look at the edges
Documents and notifications are easy to miss
Listen to the sound
Names, place names, and background sounds may be included
Combine with post text
Text can reinforce information that is weak in the photo alone
Does It Connect to Past Information?
Even if the current post has no personal information, it is dangerous if it connects to past posts.
If there is an old handle, the same icon, the same speech habits, the same hobbies, or talk about the same region, separate accounts can become linked.
Connecting element
What to check
Handle
Whether it resembles a past account
Icon
Whether it is reused from a real-name account
Profile text
Whether the same self-introduction is used
Writing style
Whether distinctive expressions stand out
Topics
Whether workplace, region, or family structure appears repeatedly
If you are worried, search your name, old handle, profile text, and already published images before posting. However, if you upload face photos or unpublished images to an external service, the checking itself may become a new record.
Check File Sharing
When sending files, there are more items to check than in a post.
Cloud sharing, social media DMs, and email attachments leave information other than the file itself.
Check item
Reason
Sending account
Real name or workplace account becomes visible
Sharing settings
Unintended people can view it
Filename
Real name, date, or place is included
Metadata
Creator, capture location, and edit history remain
Notifications and logs
Who opened it and when is recorded
For files that need anonymity, the basic rule is not to send them from a real-name account you normally use.
Final Questions Before Publishing
At the end, check the following questions together.
Question
Purpose
Whose information appears in this post?
Prevent involving people other than yourself
Would it be a problem if it remained years later?
Keep long-term publication in mind
What does it connect to if searched?
Look at correlation with past information
Is it acceptable if it is screenshotted?
Assume it cannot be fully deleted
Does it connect to a real-name account?
Prevent account correlation
For posts you are unsure about, options include not publishing, reducing information, waiting, narrowing the publication scope, or using a different expression.
Do Not Overtrust Publication Scope
Even if the publication scope is set to "friends only" or "limited," you cannot be completely at ease.
Screenshots, quotes, forwarding, sharing setting changes, and display on the other person's device can spread it beyond what you expected. Limited publication is a way to reduce risk, but it does not mean you can fully control it after publication.
Setting
Remaining risk
Friends only
Friends may save or forward it
Limited link
It spreads if more people learn the link
Temporary post
It remains through screenshots
Private group
Members may take it outside
Instead of thinking "it is limited, so it is fine to publish," think "reduce the information to a range that will not cause trouble even if it spreads."
Rushed Posts Are More Dangerous
Pre-publication checks are easiest to miss when emotions are strong.
You are angry. You are anxious. You want to tell someone immediately. You want to publish a photo or screenshot in the moment.
At times like this, names, notifications, places, and information about the other person are easy to overlook.
Situation
Likely mistake
Angry
Writing too many details that reveal the workplace or other person
Rushed
Missing notifications in screenshots
Wanting help
Revealing too much about an address or routine places
Wanting to share on the spot
Current location or companions become visible
For posts you are unsure about, wait even a few minutes. Simply waiting can make information that should be removed visible.
Summary
In a pre-publication check for individuals, check names, faces, addresses, schools, workplaces, family, friends, photos, videos, past posts, and file sharing.
What matters is not single pieces of information, but combinations.
No face appears, but routine places do. No name appears, but the old handle is the same. Nothing appears in the photo, but the post text mentions a school event. Anonymity breaks through combinations like these.
Information that spreads after publication cannot be fully taken back.
A few minutes before publication can reduce major problems later.
