To block someone on TikTok, follow these steps:

1. Open the TikTok app on your device.
2. Go to the profile of the person you want to block. You can do this by tapping their username from your feed, notifications, or by searching for them using the search bar.
3. On their profile page, tap the Share button (an arrow icon) located at the top right corner of the screen. Sometimes, the three dots menu may be available instead, and you can tap that.
4. From the menu that appears, select Block.
5. Confirm your choice by tapping Block again in the confirmation prompt.

Once blocked, that user will no longer be able to view your posts, follow you, send direct messages, or interact with your content through comments or likes

. If you want to unblock someone later, go back to their profile, tap the Share button or three dots, and select Unblock , then confirm

. This method works on both iPhone and Android devices
