Quick answer
Blocking on TikTok is a one-directional wall: it cuts nearly every way the blocked account could interact with you or see your content, without them being told it happened. It takes only a few taps from their profile, and it can be undone later if needed.
How do you block someone on TikTok?
The most direct route is from the account's profile:
- Open the profile of the account you want to block, either by tapping their username or searching for them.
- Tap the three-dot menu or arrow icon in the top right corner of their profile.
- Select Block from the menu that appears.
- Confirm the block when prompted.
TikTok's Help Center also documents two shortcuts for blocking without visiting a full profile first: tapping and holding one of their comments on your video and selecting the block option from the menu that pops up, or opening a direct message conversation with them, tapping their name at the top, and selecting Block from there. All three routes lead to the same result.
What actually happens once you block someone?
Blocking is deliberately broad. According to TikTok's Help Center, once you block an account:
- They can no longer view your profile or any of your videos.
- They can no longer send you direct messages.
- Your account stops appearing for them in TikTok search, and theirs stops appearing for you — the block works in both directions for visibility.
- Any comments or likes they previously left on your videos are automatically removed.
- They can no longer view or join your LIVE, comment in it, or send gifts during it.
- If you were following each other, the follow relationship is broken.
Caveat: blocking is specific to TikTok. It does not affect any conversation you have with that person on another app (WhatsApp, Instagram, SMS, and so on) — if the harassment is happening across multiple platforms, you'll need to handle each one separately.
Does the person know you blocked them?
No. TikTok does not send a notification telling someone they've been blocked. In practice, they may work it out on their own — your profile disappearing from their search results, or a message failing to send, are common tells — but there is no direct alert from TikTok announcing the block. This makes blocking a reasonably discreet way to cut contact, compared to more visible options like publicly calling someone out.
If you're dealing with harassment or unwanted contact rather than just wanting quieter comments, blocking is usually the right first step, but it isn't the only tool TikTok gives you. Reporting a specific video, comment, or account is a separate action from blocking and flags the content for TikTok's review, which blocking alone does not do. The two are worth using together when the behaviour crosses into harassment, spam, or a safety concern, rather than treating a block as the end of the process.
How do you unblock someone on TikTok?
If you change your mind, or blocked an account by mistake:
- Open Settings and privacy from your profile.
- Tap Privacy.
- Tap Blocked accounts to see your full blocked list.
- Find the account and tap Unblock.
Unblocking restores their ability to view your public profile, message you, and interact normally with your content — but it does not automatically restore a previous follow relationship. If you were following each other before the block, both accounts would need to follow each other again.

How do you block someone on TikTok?
Go to their profile, tap the three-dot menu (or arrow icon) in the top right, select Block, and confirm. You can also block from a comment or a direct message conversation.
Does the person know you blocked them on TikTok?
No, TikTok does not notify a blocked person. They may notice indirectly, since your profile and messages become inaccessible, but there's no direct alert.
What happens to old comments and likes when you block someone?
Any comments and likes the blocked account previously left on your videos are automatically removed once you block them.
Can you unblock someone on TikTok later?
Yes. Go to Settings and privacy > Privacy > Blocked accounts, find them, and tap Unblock. This does not automatically restore a previous follow relationship.
