Why doesn't Tik Tok have an independent topic?

The platform's own topic is gone, that is, Tik Tok's topic name appears advertising words, challenging the sponsor's video.

Advertising words appear in the topic name of 1.Tik Tok: advertising words appear in the topic name of Tik Tok, and the official of Tik Tok will automatically delete the topic.

2. Challenge the sponsor's video problem: There is something wrong with the video that challenges the sponsor, resulting in the topic not being listed.
