There are many reasons why you get blocked on TikTok, if you suspect you are blocked, try the tips below.
How to know if someone blocked you on TikTok
Try searching for the username
This is the basic way, you just need to find the username on the TikTok app bar and enter the username you want to check. If you don't see their account name appear, you may have been blocked. But if they delete their account, you won't be able to find it.
So in many cases, you will also be confused between being blocked by a user and that they have deleted their account. In this case, if you want to know clearly whether the user deletes their account or they block your account. Find their account name with guest mode or use another TikTok account and find their account name.

In this case, go to your personal page > select the icon 3 bars in the upper right corner > Settings and privacy > Activity center > under Past activity and interactionscheck items such as View, comment, search and mention history.

Check old messages
If the interaction between you and the blocker is high, you probably messaged them before they blocked you. So, go to your Mailbox and find the message content to see if there's anything left.
