If You Block Someone on Twitter, Do They Know?

How a Twitter user might discover you blocked them

Whether you're facing harassment, spam from bots, or just unpleasant interactions from other Twitter users, blocking accounts can put a stop to it. But if you block someone on Twitter, do they know you blocked them?

How Blocking Works on Twitter

You can block any user on Twitter by navigating to their profile (on the web or on the official mobile app) and selecting the three vertical dots located beside the Follow/Following button.

A dropdown list of options appears, including one labeled Block @username.

Blocking a user prevents them from following you from that account. If they try to follow you, Twitter displays a message that says, "You have been blocked from following this account at the request of the user."

Does Twitter Notify You When Somebody Blocks You?

Twitter won't send you a notification if someone blocks you. The only way you can tell for sure you've been blocked is to visit the other user's profile and see the Twitter block message.

If you suspect you were blocked by someone, it's up to you to investigate and confirm it. If you don't even realize that a particular user is missing from your timeline, you might never even know you've been blocked.

Keep in mind tweets from a user that you blocked are removed from your timeline if you were previously following them. Twitter also automatically removes the user you blocked from your followers list. Likewise, your tweets no longer show up in a blocked user's timeline if they previously followed you.

Keeping Track of Your Blocked Users

If you block a lot of users, Twitter has some advanced options you ​can take advantage of to keep track of everything. You can export a list of your blocked users, share your list with others, import somebody else's list of blocked users, and manage your list of imported block users separately from your full list.

To access this, select your small profile picture at the top of the screen and go to Settings and privacy > Blocked accounts. You should see a list of blocked users plus an Advanced options link, which you can select to either export your list or import one.

Is There a Way to Prevent Someone From Finding Out You've Blocked Them?

There's no way to keep a user from finding out you've blocked them. If you block someone and they visit your profile or try to follow you again, they will a message telling them they're blocked. But, you can make your Twitter account private. That way, you can control who follows you and you can avoid blocking people in the first place. Here's how you can make your Twitter profile private.

Twitter Muting: A Friendlier Alternative to Blocking

If you really want to stop communication between you and a particular user, blocking is usually the best way to achieve that. However, if you simply don't want to be bothered by a particular user, but you don't want to permanently end the relationship, you can simply mute them.

Muting is just what it sounds like. This handy feature essentially allows you to temporarily (or perhaps permanently) filter out all the noise that another user is making in your main feed or @replies without having to actually unfollow or block them.

To do this, just select the three vertical dots on a user's profile and select Mute @username.

The muted user can still follow you, see your tweets, and even @reply to you, but you won't see any of their tweets in your feed (if you follow them) or any of their @mentions in your notifications. But, muting has no effect on directing messaging. If a muted account messages you, it still shows up in your DMs.

Remember that the social web is a very open place, so never sharing private information online, coupled with managing your privacy settings, is important if you don't want to be as open as the social web encourages you to be. If you believe a blocked user may also be a spammer, you can report the account to Twitter.
