# What Happens When You Block Someone on X?

Source: https://trygrowx.app/glossary/block (updated 2026-11-04)

Blocking an account on X stops it from following you, liking, replying to or reposting your posts and sending you direct messages, according to [X's help page on blocking](https://help.x.com/en/using-x/blocking-and-unblocking-accounts). If your posts are public, a blocked account can still see them. If your posts are protected, it cannot.

## What a blocked account can and cannot do

| Action                                  | Blocked account |
| --------------------------------------- | --------------- |
| See your public posts                   | Yes             |
| See your protected posts                | No              |
| Follow you                              | No              |
| Like, reply to or repost your posts     | No              |
| Send you a direct message               | No              |
| Add you to a list or tag you in a photo | No              |

X does not send a notification when you block someone. If they visit your profile, they will see that they have been blocked.

The "can still see public posts" rule arrived in November 2024, when X changed blocking so it limits engagement while public posts stay visible, as the [Associated Press reported](https://ksat.com/business/2024/11/04/you-may-have-blocked-someone-on-x-but-now-they-can-see-your-public-posts-anyway). Before that, blocked accounts could not view your posts while logged in.

## Example

An account replies to every post you make with insults. You block it: its replies stop, it unfollows you automatically and its messages stop arriving.

## Why it matters for growth

- **It keeps your replies healthy.** Spam and abuse under your posts put off the people you want to reach.
- **It protects your energy.** Arguing with bad-faith accounts takes time that is better spent on posts and real conversations.

Block freely for abuse and spam. For accounts that are simply noisy, [mute](https://trygrowx.app/glossary/mute) is gentler.

## Frequently asked questions

### Can I undo a block?

Yes. Open their profile and choose Unblock.

### Should I block or mute?

Block spam, harassment and bad-faith accounts. [Mute](https://trygrowx.app/glossary/mute) accounts you simply want to see less of, since muting changes nothing on their side.
