How to know if someone blocked you on X (Twitter)

Yes, when their account is public. X began rolling out a new rule over the weekend of 2 and 3 November 2024, and since then a block no longer hides their public posts from you.

X's help page on blocking lists what a block still stops. Once you're blocked, you can't:

• follow them
• like, reply to or repost their posts
• send them a DM
• add them to a list or tag them in a photo

That breaks the old test: you're blocked if you can't see their tweets. Plenty of guides still describe a block that way, and as of October 2026 so do two of X's own help pages.

If their account is protected, you see no posts at all. Only followers can read a protected account, and X won't let you follow an account that blocked you.

Two other tests you'll see recommended are searching for the account and mentioning it. X's help pages back neither. And the "You're blocked" notice older guides quote isn't in the text of X's web or Android app any more.

No. X keeps a list of the accounts you blocked, under Settings and privacy, then Privacy and safety: how to see and unblock them. It has no page for the other direction.

No app can build one either. X tells an app which accounts you've blocked, and nothing about who blocked you. Checking profiles from outside fails too, because only the blocked account is stopped from following. To everyone else the profile looks normal.

Some sites that promise a block list show a fake X login screen and keep what you type into it. Never type your X password anywhere but x.com: see what a tracker should never ask you for.

If what you noticed is a missing follower, or that you no longer follow someone you never unfollowed, this table shows what each action changes on your side. It assumes you followed each other and that their account is still there.

Say that on Sunday you had 863 followers and followed 427 accounts. By Wednesday it's 862 and 426, and you haven't unfollowed anyone. If the same account is missing from both lists, it wasn't a plain unfollow.

Then open their profile. An error when you try to follow means a block, and a profile that lets you follow again means a soft block. If the profile itself is gone, that's the next section.

A soft block is a block followed straight away by an unblock. The unblock puts neither follow back, so the person has dropped you as a follower without leaving you blocked.

"Remove this follower" does half of that: it ends your follow and leaves theirs alone. As of October 2026, X's Following FAQs describe it as a web-only option.

When you're blocked, their profile is still there. If the account was deleted or deactivated, X says "This account doesn't exist", and if X suspended it, the profile says "Account suspended". You see the same whether they blocked you or not.

Among the accounts UnfollowMonkey tracks, a lost follower is more often an account that's gone than an unfollow or a block.

Deactivating doesn't delete an account at once. X keeps it for 30 days and deletes it only if the owner hasn't logged back in by then, so a profile that's missing today may be back within the month.

X also removes locked accounts from follower counts, which is one of the reasons your follower count can drop with nobody unfollowing or blocking you.

Ours can't, and neither can any tracker that reads your follower list from outside your account. When a follower blocks you, they drop out of that list exactly as if they'd unfollowed, and the list is what we compare from one check to the next.

So we look the missing account up, find it still active, and DM you "@name unfollowed you 🙈 💔", with a line under it such as "They followed you for about 3 months."

UnfollowMonkey

@your_ex unfollowed you 🙈 💔

They followed you for about 3 years.

@moon_signals_88 got suspended 😱

We tell you which follower is gone and whether their account still exists, and their profile tells you the rest.

Two things never reach us: a block from someone who didn't follow you, because they were never on the list, and anything that happened before your first check.

How soon you hear depends on your plan: once a month on Free, once a week on Chimp Max, every day or faster on the other paid plans. How to see who unfollowed you goes through the whole method.
