It is possible to track a TikTok account. There are various methods that can be used to do this, including using third-party apps and websites, as well as looking through the account's public information. Third-party apps and websites can offer users the ability to see detailed information about another user's activity on TikTok.
This includes things like how many videos they have posted, how many likes and comments they have received, and who their followers are. Some of these services also allow users to see private information about an account, such as their email address or phone number. Looking through the public information on an account can also give some clues about its owner.
For example, if someone has their real name listed in their profile then it may be possible to find them on other social media platforms or even do a reverse image search to find out more about them. Checking the location settings on an account can also reveal where in the world the user is based.
