What blocking does on TikTok
When you block someone on TikTok, that person cannot see your profile, videos, or comments. They cannot send you direct messages, and they cannot find your account through search. If they try to visit your profile directly, they will see a message saying the account is not available. Blocking is permanent until you unblock them — there is no time limit.
Blocking is different from muting or restricting. Muting hides someone's videos from your feed without them knowing. Restricting lets someone follow you but limits what they can see and comment on. Blocking is the strongest action and is visible to the other person if they try to interact with you.
Key Takeaways
- You can block someone from their profile, from a comment they left on your video, or from a direct message conversation.
- The person you block will not receive a notification that you blocked them, but they will see the block if they try to visit your profile.
- You can unblock someone at any time by going to your blocked accounts list in Settings.
- Blocking someone does not delete comments they already left on your videos — you must delete those separately.
- If someone blocks you, you cannot see their profile, and any previous direct messages will remain in your chat history but you cannot send new ones.
How to block someone from their TikTok 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 page. A menu will appear with several options. Tap "Block" from that menu. TikTok will ask you to confirm — tap "Block" again to finish.
After you block them, their profile will no longer appear in your search results, and any videos they posted will be hidden from your feed. If you were following them, TikTok will automatically unfollow you from their account.
How to 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, tap the three dots next to their comment. A menu will appear with options including "Block user." Tap that option and confirm. This blocks them from your account entirely, not just from commenting on that one video.
You can also block someone from a direct message conversation. Open the conversation, tap the person's username at the top of the chat, and then tap the three dots. Select "Block user" and confirm. The conversation will remain in your message list, but you will not receive new messages from them.
What happens to comments and messages after you block someone
Comments that a blocked person already left on your videos will stay visible to other users, but the blocked person cannot see your replies to their comment. If you want to remove their comment entirely, you must delete it manually. Tap the three dots next to the comment and select "Delete" — this is separate from blocking.
Direct messages from before you blocked someone will remain in your chat history. You can read them, but you cannot reply. If you want to delete the entire conversation, swipe left on the chat (on iPhone) or long-press it (on Android) and select delete.
How to see who you have blocked and unblock them
Open TikTok and go to your profile by tapping the person icon at the bottom right. Tap the three lines in the top right corner to open the menu. Scroll down and tap "Settings and privacy." Tap "Privacy," then "Blocked accounts." This shows a list of everyone you have blocked.
To unblock someone, find their name in the list and tap the minus sign next to it. Confirm that you want to unblock them. Once you unblock someone, they can see your profile and videos again, and they can send you messages and comments.
What the blocked person sees
When someone you have blocked tries to visit your profile, they will see a message that says "User not found" or "This account is not available." They cannot search for you by username and have your profile appear in results. If they had your profile link saved, clicking it will show the same message.
The blocked person will not get a notification saying you blocked them. However, if they were following you and suddenly cannot see your profile, they may realize they have been blocked. If they try to message you, they will see that messages cannot be sent.
Blocking versus other privacy controls
TikTok offers several ways to control who sees your content and interacts with you. Muting hides someone's videos from your feed without them knowing — they can still see your profile and message you. Restricting lets someone follow you but hides your comments from their view and prevents them from seeing when you are online. Blocking removes all access — they cannot see your profile, videos, or comments.
If someone is harassing you, blocking is the right choice. If someone just posts content you do not want to see, muting is faster and less confrontational. If you want to limit someone's interaction without fully blocking them, restricting is the middle ground. You can change your mind about any of these actions at any time.
Frequently Asked Questions
Can someone tell if I blocked them?
They will not get a notification, but if they try to visit your profile or search for you and cannot find you, they may suspect it. If they had your profile saved and the link no longer works, that is another sign. There is no way for them to know for certain without trying to interact with you.
If I block someone, will they see my old comments on their videos?
Your comments will remain visible on their videos, and they can still see them. Blocking only prevents future interaction and hides your profile from them. If you want to remove a comment you left before blocking them, you must delete it from your own profile.
What happens if I block someone and then unblock them later?
Once you unblock them, they can see your profile and videos again. However, any comments or messages you deleted while they were blocked will not reappear. They will not be notified that you unblocked them.
Can I block someone without them knowing my account exists?
If you block someone before they ever see your profile, they will have no way to know you exist on TikTok. Blocking only prevents interaction going forward — it does not erase any past contact. If you have messaged them or commented on their videos before blocking, they will still see that history.
Does blocking someone on TikTok block them on other platforms?
No. Blocking on TikTok only affects TikTok. If the person also has accounts on Instagram, YouTube, or other platforms, they can still follow you and interact with you there. You would need to block them separately on each platform.
