Have you ever noticed you're suddenly not seeing a person's posts and stories any more?
Or maybe you click on a friend's profile and you can't see their page because they're private and you aren't following them - even though you thought you were.
And then you have to re-follow them, and it's a bit awkward.

Because while unfollowing somebody won't send them a notification, sending them a new follow request will.
So why does this happen? Is Instagram unfollowing people on your behalf?
One Reddit user wrote: "My Instagram account [appears to have been] unfollowing people without my consent for several months, I did change my password, turn on two factor authentication, checked the authorised apps and even contacted Instagram.
"I really don't know what to do any more and I really don't want to start over my Instagram."
Another user suggested it could be that some people had blocked and then unblocked the person, meaning they didn't follow them any more.
But the original poster said it was happening too many times for this to be the case.
A spokesperson for Instagram confirmed the social media platform would never unfollow people on anyone's behalf.
So what is actually happening, then?
One possibility is that a third party service could be following and unfollowing via your account.
If you have ever allowed an application access to your account, they could be able to perform actions on your behalf.
You can check if this is the case by going to the Security option within your settings in the app, and scrolling to Apps and Websites.
This will tell you if you have allowed any third parties access, and will give you the option to remove this.
It is also possible your account may have been hacked and somebody else is performing the actions on your account.
If you suspect this may be the case, it's wise to change your password, and also check your account to make sure any suspected hackers haven't deleted anything or left anything unwanted behind.
The most likely reason is you may have unfollowed somebody by accident e.g. if you've put your phone in your pocket without leaving the app or locking your screen.
