I have reason to believe TikTok is using my likeness without permission.

Basically, when I’m typing in DM gifs pop up but recently I noticed there’s specific deepfake type of gifs they keep throwing up every time I start typing a single letter. It does not appear on any other accounts that I have so I’m wondering what this shitty feature is and how to turn it off? I don’t post my face on tiktok and I don’t use avatars.
