Hello, we are developing a service for promoting accounts in TikTok.
How to arrange everything correctly (TikTok brand name, their logo), what can be used and in what context on the service website (on the main page of the landing page) in order to avoid responsibility.

For example, the same instaplus.me uses the Russian name "Instagram" and lives in peace. How to do it right, tell me who is strong in this matter.
