How to find out if someone has deleted you on Facebook, Instagram and Twitter

Ever been searching for an old friend, colleague or ex on Facebook, only to realise they've quietly unfriended you? Well now you can be alerted when you someone has pressed the dreaded "unfriend" button.

Who Deleted Me, a new app and Google Chrome extension, will alert you when someone removes you as a friend.

Unlike Twitter and Instagram, where follower lists tend to be public, Facebook's data is more closely guarded - the company does not offer its own feature to find out who has deleted you, and presumably, doesn't want to.

Who Deleted Me is not the first app claiming to provide a list of "unfriends", but has generated serious attention since launching last week.

At present, however, its servers appear to be down with the sheer volume of traffic to the service.

How to find out if someone has deleted you

Here's how to check who has block or unfollowed you on Facebook, Twitter and Instagram

On Facebook

Facebook's greater focus on individual privacy means that it is not as quick or easy to find out if someone has deleted you as a friend.

Who Deleted Me, an iOS and Android app and Chrome extension, is the latest in a range of apps that claims to tell you if someone deletes you.

However, the service will only reveal people that have deleted you after you have downloaded the app, not before.

Other apps and extensions have launched in the past, and become obsolete as Facebook changes its programming code, so this app may not last for long. Who Deleted Me says it is working on getting its servers back online.

1. Download the app for iOS or Android, or the Chrome extension
2. Log in to Facebook via the app
3. Hit "Show Me Who" to see who has deleted you since installing the app. It will also tell you who is a new friend.

On Instagram

It is easier to check up on one's followers on Instagram, which has a more public list of friends.

Unfollowers.com allows a user to log in with their Instagram account and keep a tab on who has stopped viewing their posts. Like Who Deleted Me, it will only track unfollows from the moment it is installed.

1. Head to Unfollowers.com and hit "Add account"
2. Click "Add Instagram Account" and enter your details. The site will not post to Instagram without your permission
3. Hit "New unfollowers" on the left hand side to see who has unfollowed you. Or in "Settings", configure the site to send you a weekly or daily email.

On Twitter

Unfollowers.com has a similar service for Twitter, allowing you to discreetly check who has unfollowed you

The site also allows you to check who is not following you back.

^{What, no follow back?}

1. Head to Unfollowers.com and hit "Add account"
2. Click "Add Twitter Account" and enter your details. The site will not post without your permission
3. Choose between options such as "New unfollowers" and "Not following back" on the left hand side to see who has unfollowed you. Or in "Settings", configure the site to send you a weekly or daily email.
