I genuinely don't think she's smart or committed enough to pull that off, just like she isn't smart enough to differentiate herself from other twitch thots. She just copycats what she sees successful e-girls doing and relies on the fame of being idubbbz's girlfriend. Before this, no one knew her because she was a good content creator, they knew her because of who she was dating and she knew it. The people giving her money now are literal simps who will pay money to any scantily clad woman who breathes in their direction, or idubbbz fans who will give his girlfriend money because he made a video about it. After all, if daddy idubbbz says an onlyfans is cool, it must be something worth supporting.
As for the domme thing, here's much more to being a domme than just having a shitty attitude, and the people looking for a dom that treats them like shit won't be able to take her seriously because she's such a dead fish. She can't even act like a normal person in her videos, how could she possibly put on an act as a domme?
