Chantal is lazy (duh). She refuses to put in any effort when it comes to creating high quality content. It's why she doesn't even try anymore to do her Creepy Pasta or Mystery Monday videos. She realized they weren't nearly as popular as her face-stuffing videos and, on top of that, those videos still forced her to put in even marginal effort.
Her videos nowadays are so basic and boring that it requires little effort. Just plop in front of the camera, stuff her face and struggle to keep a train of thought going while she continues to choke down whatever she's eating.
It's amazing that Chantal actually puts in less overall effort the more her channel grows than she did at the start when only a couple thousand were watching. Most bigger YT channels, those who see it as a legitimate career, only improve their effort the more their channel grows. Not Chantal, though! It wouldn't surprise me if, in a few months, her channel wasn't just her eating, grunting and farting without ever uttering a word. I mean, let's be real, she's kinda there already.
