If she doesn’t wanna shoot for her site anymore, that’s cool. But I do wish she’d reconsider her onlyfans.
According to Mumblez, she just wasn't that into it. People were paying for OnlyFans to be a more exclusive, more intimate look at her life. She didn't know how to cater to that expectation, and eventually she just stopped bothering with it.
Her best videos on nikkisims.com, imho, were the ones where she forgot about the camera and just was herself. Mumblez had hoped that she would open that side of herself up through completely running her OF account on her own. That's part of the reason why he started backing away from interacting with her in the videos on the main site, as well. Nikki was comfortable with posing and performing a routine of looks and behaviors, but getting real on camera was not something she allowed herself to do very often.
"Bate Car" being an exception - note: she never looks at the camera in that vid, she's not at home or on set, she's somewhat focused on the road and not on the fact that she's being recorded and there is a naughtiness factor of her getting away with something - in other words: there are no interior distractions to take her out of her own pleasure. "Hitachi Torture" is another good example of her not being able to focus (literally blindfolded, bound and stimulated) on the camera and being focused on the present. In both of these videos she gets out of her own head and effortlessly her innate, authentic human sexuality comes out. In fact, most of the BDSM/spanking videos are her most expressive and authentic content. I'm not into kink, personally, but I am into realness and these videos offered more in the line of real expression from her than almost anything else she did.
Some people need privacy to get out of their own self-consciousness, and others need the right kind of distraction to pull them out of it. I think she was the latter.
This ended up being more of a rant on woulda-coulda-shoulda.
TL;DR - OnlyFans was a bad fit for her and she didn't like it.
