What are the benefits of Tik Tok praising others?

It is no good for Tik Tok to praise others, because praise is only a way to express his love or support, and there is no direct benefit or return to the person he likes. Tik Tok is a social media platform where users can post their own video works and other users can watch and like them. Like can increase the exposure and popularity of the video, but for the likes, there is no substantial benefit.
