Why do people ragebait?, ninetookchesgirl

Okay i have no idea if this is "too niche" but there‘s this dude on tiktok who‘s "ragebaiting" by saying insane stuff. He obviously gets death threats, he got doxxed and people are making fun of his face. I showed some of his tiktoks to my boyfriend and we asked ourselves why would anyone show their face while ragebaiting? what happened to digital footprint? Is this a kink/fetish? Is he just mentally ill?? Im sooo confused😭
