TikTok is a Highly Biased Social Platform! It is also run by an incompetent administration, who does not understand the laws as it pertains to the legalities of copyright law. I placed a video presentation of a song, which was fully within the Public Domain, yet TikTok muted it and replaced my original soundtrack with someone else's soundtrack. This doubled the illegality of the process. Not only did TikTok Administration not remove the illegal soundtrack placed on my video, but refused to even acknowledge both if its errors.
I finally removed all my videos from TikTok, and deleted my account. Not a honest Social Platform to get involved with!
