We all know the rule.
Once it’s online, it’s probably there forever.
And yet...
We still post everything.
Our food.
Our holidays.
Our relationships.
Our breakups.
Our location.
Our opinions.
Our gym progress.
Our bad takes from 2019.
Sometimes even our boarding pass.
We know screenshots exist.
We know people save things.
We know old posts can suddenly come back years later.
Still, we post first and think later.
That is kind of strange when you think about it.
We Grew Up Posting in Real Time
For younger internet users, posting feels normal because it has always been part of life.
Something happens.
You take a photo.
You upload it.
Done.
The internet became less like a place we visit and more like a running diary that other people can read.
The problem is that diaries used to stay inside a drawer.
Instagram does not.
TikTok does not.
X definitely does not.
Even something you delete may already exist somewhere else.
A screenshot.
A repost.
A backup.
A group chat.
Or somebody’s camera roll because they thought your embarrassing story was funny.
The Version of You Online Might Be Old
Here’s another weird thing.
People change.
Your opinions at 18 may not be the same at 25.
Your humour changes.
Your friends change.
Your job changes.
Your life changes.
But the internet can keep an old version of you frozen in time.
One random post from years ago can suddenly become the first thing someone sees when they search your name.
And context disappears really fast online.
You might remember why you posted something.
Everyone else just sees the screenshot.
We Share More Than We Realise
Sometimes it isn’t even the actual post that matters.
Look at the background.
A house number.
A school logo.
An office access card.
A laptop screen.
A car registration number.
A location tag.
A regular coffee shop.
Individually, these things look harmless.
Put enough of them together and someone can learn quite a lot about you without ever speaking to you.
That does not mean we need to stop posting.
The internet would be pretty boring if everyone suddenly became invisible.
But maybe we need a slightly different habit:
Post like a stranger might see it one day.
Not just your friends.
Not just your followers.
A future employer.
A scammer.
Someone you have never met.
Or maybe even future-you, five years from now, staring at an old post and asking:
Why did I put this on the internet?
Because the internet never forgets.
Unfortunately, neither do screenshots.
