Blocking stops someone from seeing your videos and messaging you

When you block someone on TikTok, they can no longer view your profile, watch your videos, send you direct messages, or see your comments. They will not receive a notification that you blocked them, but if they search for your account, they will see a message saying the user is unavailable. Blocking is permanent until you choose to unblock them — there is no time limit.

The block applies only to that person's account. If they create a new account, they can still find and watch your public videos unless you block the new account too. TikTok does not notify you when someone tries to view a blocked account, so you will not know if they attempted to contact you after the block.

Key Takeaways

  • Blocking someone prevents them from messaging you, commenting on your videos, and viewing your profile, but does not delete past interactions.
  • You can block a user from their profile, from a comment they left, or from a direct message — each method takes two taps.
  • Blocked users can still see your public videos if they log out or use a different account, so blocking is not the same as making your account private.
  • You can unblock someone at any time by going to your blocked list in Settings, and they will not be notified when you unblock them.
  • If someone is harassing you repeatedly or threatening you, blocking combined with reporting the account gives TikTok more information to take action.

Block someone from their profile

Open TikTok and search for the person's username or navigate to their profile. Tap the three dots in the top right corner of their profile — this opens a menu with several options. Select "Block" from the menu. A confirmation message will appear asking if you are sure; tap "Block" again to confirm.

After you block them, their profile will show a message saying "User unavailable" if they try to search for you. Any comments they left on your videos will remain visible to you, but they will not be able to leave new comments or see your future posts.

Block someone from a comment or direct message

If someone leaves a comment on one of your videos that you want to block them for, long-press or tap and hold on the comment. A menu will appear with options including "Block user." Tap it, and the confirmation screen will appear — tap "Block" to finish.

You can also block someone from a direct message. Open the message thread with that person, tap the three dots in the top right corner of the chat, and select "Block." This blocks them from messaging you and removes the conversation from your inbox.

The difference between blocking and reporting

Blocking is a personal action that stops one person from contacting you. Reporting is a flag to TikTok's safety team that the account is breaking the platform's rules — for example, harassment, threats, sexual content involving minors, or spam. You can do both at the same time.

When you report an account, TikTok reviews it to decide whether to remove the content, suspend the account, or take no action. Reporting does not automatically remove the account or notify the person who reported it. If someone is harassing you, reporting gives TikTok context about the behavior, which can lead to action against the account even if you later unblock them.

What happens to past interactions when you block someone

Comments the blocked person left on your videos stay visible to other users and to you, but the blocked person cannot see them anymore or reply to them. Direct messages you exchanged before blocking remain in your chat history, but the blocked person cannot send new messages or see that you have read their old ones.

If you had liked or commented on their videos before blocking, those interactions remain on their account. Blocking does not erase the history — it only stops future contact and visibility.

How to unblock someone

Open TikTok and go to your profile by tapping the person icon at the bottom right. Tap the three lines (menu) in the top right corner and select "Settings and privacy." Scroll down and tap "Blocked accounts." You will see a list of everyone you have blocked. Find the person you want to unblock, tap the X or "Unblock" button next to their name, and confirm.

Once you unblock someone, they can see your profile and videos again, and you can message each other. They will not be notified that you unblocked them. If you block them again later, you will need to go through the same process.

When blocking is not enough

If someone is creating multiple accounts to contact you after you block them, or if they are threatening you, blocking alone may not solve the problem. Report each new account and document the behavior by taking screenshots of the messages or comments. If the harassment involves threats of violence or sexual content, you can also report it to local law enforcement.

TikTok's reporting system is designed to catch patterns of abuse. The more accounts you report from the same person, the more likely TikTok is to investigate and take action. Keep your own record of dates and usernames in case you need to reference them later.

Frequently Asked Questions

Can someone tell if I blocked them?

They will not receive a notification, but they may figure it out if they try to find your account and see "User unavailable." If they ask you directly, you do not have to tell them. Some people realize they are blocked when they cannot see your profile or send you messages.

Will blocking someone delete our old messages?

No. The messages stay in your chat history, but the blocked person cannot send new messages or see that you have read the old ones. You can delete the conversation yourself if you want to remove it from your inbox.

Can a blocked person see my videos if they log out?

Yes. Blocking only affects that specific account. If they log out and watch as a guest, or create a new account, they can still see your public videos. If you want to prevent this, you would need to make your account private, which limits who can see your videos regardless of whether they are blocked.

What should I do if someone keeps making new accounts to message me?

Block each new account and report it. Take screenshots of the messages with the usernames and dates visible. If the messages contain threats, report them to TikTok and consider reporting to local police. Document the pattern so you have evidence if you need to escalate.

Does blocking someone remove their likes or comments from my videos?

No. Their past likes and comments stay on your videos where other people can see them. They just cannot leave new comments or like your future videos. If you want to remove a specific comment, you can delete it yourself.
