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

Yes, when their account is public. X changed the rule over the weekend of 2 and 3 November 2024, and 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, the one that says 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 notice older guides quote has since been reworded.

No. X keeps a list of the accounts you blocked, under Settings and privacy, then Privacy and safety, then "Blocked accounts". 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 sees the notice. 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. Before you give any tool your X password, read 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. On their profile, a notice means a block, and a normal profile that lets you follow again means a soft block. If the profile itself is gone, that's the next section.

Soft block means 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, with the notice on it. If the account was deleted or deactivated, you get a message that it doesn't exist, and if X suspended it, a message that it's suspended. Everyone sees those two messages, blocked or not.

Among the accounts UnfollowMonkey tracks, a lost follower is more often an account that's gone than an unfollow or a block. Of the more than 9,000 follower losses we recorded between May and October 2026, 53% were suspended, deleted or deactivated accounts.

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. About a third of the followers we recorded as deleted came back later.

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

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 scan.

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