X (Twitter) doesn’t give you a list of the people who aren’t following you back. To see every account you follow that doesn’t follow you back, connect your account in Who Unfollowed Me and open Manage → Sort Accounts You Follow. The list is on Fedica’s Grow plan and works the same way on X, Bluesky, Mastodon, and Pixelfed.
Checking by hand works one account at a time: open the profile and look for the Follows you label next to the handle. No label, no follow back.
That gets old fast once you follow a few hundred accounts. It also matters more as the list grows, because X stops most accounts at 5,000 follows until their own follower count catches up, and every one-sided follow is holding a spot you might want for someone else.
Key Takeaways
- X has no built-in non-follower list. The Follows you label checks one profile. Sort Accounts You Follow in Who Unfollowed Me lists every non-follower at once.
- Not following back isn’t the same as unfollowed. Non-followers are who isn’t following you back right now, while unfollowers are a dated list that only starts the day you connect.
- Unfollowing a non-follower costs you no followers. They weren’t following you, so the only thing you lose is their posts in your feed.
- X publishes a follow limit of 400 a day and no unfollow limit. Fedica’s guidance is to keep unfollows under 400 a day as well, because X bans bulk and aggressive unfollowing.
- Same list on Bluesky, Mastodon, and Pixelfed, in the same hub as X.
How to see who is not following you back on X (Twitter)
X (Twitter) shows your Following and Followers lists on separate screens and never compares them for you. You can compare them yourself, one profile at a time, or let a tracker compare the whole list.
Check one account with the “Follows you” label
Open the profile of someone you follow. If they follow you, X shows a small Follows you label next to their handle.
That’s fine for checking a friend or a client. Across a few hundred accounts it turns into hours of tapping, and X doesn’t let you filter your Following list by the label.
See every non-follower in Who Unfollowed Me
- Create your account in Fedica.
- Connect your X account. You sign in on X’s own screen through the official X API, and Fedica never asks for your password.
- Open Manage → Sort Accounts You Follow (included on the Grow plan).
- Read the list of accounts you follow that don’t follow you back, and unfollow the ones you don’t need.
The non-follower list is ready at signup, because it compares the lists you have today. You don’t wait for history to build the way you do with unfollowers.
Not following you back vs unfollowed you
A non-follower is an account you follow that doesn’t follow you back. An unfollower is an account that used to follow you and stopped.
The two overlap less than people expect. Someone you followed last week who never followed back is a non-follower, but never an unfollower. Someone who followed you and then left is an unfollower, and if you still follow them, they’re a non-follower too.
Fedica keeps them in two places:
- Manage → Sort Accounts You Follow
Who isn’t following you back right now, taken from your current follows. - Manage → Unfollows/New followers
Who left, by name and with the date. Tracking starts the day you connect, so Who Unfollowed Me can’t show unfollows from before signup.
The two lists answer different questions. Sort Accounts You Follow is for cleaning up your own following, and Unfollows/New followers tells you about your audience, like who left after a post that didn’t land.
How to check who doesn’t follow you back on Bluesky, Mastodon, and Pixelfed
Bluesky, Mastodon, and Pixelfed don’t have a built-in non-follower list either, so the native check on each one is profile by profile.
Who Unfollowed Me has the same Sort Accounts You Follow list for all three. Connect each profile once, and the non-followers for every network sit in one hub next to your X account.
Unfollower tracking works there too. Unfollows/New followers names who left you on Bluesky, Mastodon, and Pixelfed, day by day, the same way it does on X.
Which non-followers to keep, and which to unfollow
Unfollowing someone who doesn’t follow you back costs you no followers. There’s no follow for them to take back, and the only thing you lose is their posts in your feed.
So the real question for each account on the list is whether you still want to read what it posts.
News accounts and big creators mostly don’t follow back, and neither do most brands or the experts you follow for their work. That’s normal. If you read them, keep them.
The rest are using up space. X lets an account follow up to 5,000 accounts, and past that the limit depends on your own ratio of followers to following (X Help Center). If you’re close to that ceiling, one-sided follows you never read are the first thing to clear.
The easiest cuts are non-followers who’ve also gone quiet. An account that doesn’t follow you and hasn’t posted in months gives you nothing either way. Fedica can flag those as well: see how to unfollow inactive Twitter accounts safely.
How many accounts you can unfollow per day on X
X publishes a follow limit but no unfollow limit. Every X account can follow up to 400 accounts per day (X Help Center), and X gives no matching number for unfollows.
That doesn’t make unfollowing unlimited. X’s automation rules say you may not follow or unfollow accounts “in a bulk, aggressive, or indiscriminate manner,” and they don’t allow automated unfollowing (X automation rules). Fedica’s guidance is to keep unfollows under 400 a day, so a cleanup doesn’t look like the follow churn X’s systems flag.
Bluesky and Mastodon set their limits differently:
| Platform | Follow limit | Unfollow limit | Source |
|---|---|---|---|
| X (Twitter) | 400 per day; 5,000 total, then based on your follower ratio | None published; bulk or aggressive unfollowing breaks X’s automation rules | X follow limits, X automation rules |
| Bluesky | Account writes capped at 5,000 points per hour and 35,000 per day; each create costs 3 points | Same write budget; each delete costs 1 point | Bluesky rate limits |
| Mastodon | 7,500 total, then 1.1 × your followers; server admins can change both | None separate; each account gets 300 API calls per 5 minutes | Mastodon PR #8807, Mastodon rate limits |
On Bluesky, a follow is a record your account creates and an unfollow deletes it, so both come out of the same write budget. At 3 points per create, the 35,000-point daily budget works out to about 11,666 follows.
Mastodon added its follow cap to the software in October 2018, and each server’s admins can change it. On a server that keeps the defaults, an account with 10,000 followers can follow up to 11,000 accounts.
Picking a safe tool for the cleanup
Who Unfollowed Me runs on Fedica, which has used the official X Enterprise API as an approved enterprise data customer since 2015 (Fedica).
Fedica doesn’t offer bulk unfollow. You unfollow one account at a time from the list, and Fedica warns you before you hit rate limits, so a long cleanup can run over a few days without putting the account at risk.
Two kinds of tools deserve a closer look before you connect your account:
- Mass-unfollow dashboards
Unfollowing hundreds of accounts in one click is the bulk behavior X’s automation rules prohibit, whichever API the tool runs on. - Browser extensions
They work inside your logged-in X session instead of X’s official sign-in screen, and X doesn’t review or audit them.
How to see who doesn’t follow you back on Instagram
Instagram doesn’t show a non-follower list in the app, so the way to compare every account at once is Instagram’s own data export, which gives you both lists. Meta’s steps from the Instagram Help Center:
- Click More, then Settings.
- Open Meta Account, then Your information and permissions.
- Click Export your information, then Create export, and pick your Instagram profile.
- Choose Export to device, select only your followers and following information, and click Start export.
Meta says the export email can take up to 30 days, and the file stays available to download for 4 days. Open both lists and look for names that appear in your following but not in your followers.
Who Unfollowed Me tracks your Instagram follower count by day. Named non-follower and unfollower lists are on X, Bluesky, Mastodon, and Pixelfed.
Frequently Asked Questions
How do I see who is not following me back on X?
Connect your X account in Who Unfollowed Me and open Manage → Sort Accounts You Follow. It lists every account you follow that doesn’t follow you back. To check a single account, open its profile and look for the Follows you label.
Will people know if I check who doesn’t follow me back?
No. Who Unfollowed Me reads your own Following and Followers lists through the official API. Nothing gets posted, and nobody on either list is told.
Does unfollowing someone on X notify them?
No. X doesn’t send a notification when you unfollow someone (X Help Center). They’d only notice if they looked through your profile or ran a tracker of their own.
Is it rude to unfollow someone who doesn’t follow me back?
Not really. They chose not to follow you, and your unfollow doesn’t take anything out of their feed. If it’s someone you know personally, keeping the follow is a courtesy rather than a rule.
What’s the difference between non-followers and unfollowers?
A non-follower is an account you follow that doesn’t follow you back. An unfollower used to follow you and stopped. Who Unfollowed Me shows non-followers in Sort Accounts You Follow and unfollowers, with dates, in Unfollows/New followers.
How many people can I unfollow per day on X?
X doesn’t publish an unfollow limit, only a follow limit of 400 accounts a day. Fedica recommends staying under 400 unfollows a day, since X’s automation rules ban bulk and aggressive unfollowing.
Is who.unfollowed.me still working?
Yes. As of September 2026, who.unfollowed.me runs on Fedica’s follower tracking, which has over 2 million users. It provides tools for finding non-followers and unfollowers on X, Bluesky, Mastodon, and Pixelfed.
Can I see who doesn’t follow me back on Bluesky and Mastodon?
Yes. Fedica has the same Sort Accounts You Follow list for Bluesky, Mastodon, and Pixelfed as it does for X, all in one hub.
To see who is not following you back on X, connect your account in Who Unfollowed Me, open Manage → Sort Accounts You Follow, and unfollow the one-sided follows you don’t read.
