I don't know if it was the rejection because she did continue checking OF pretty much everyday. Could be some cold feet creeping in. Once, if/when she starts OF, her relationship with her community will change forever. Not that she doesn't know how her community feels about her, the first day of her NSFW discord was probably the most honest they've been with each other.
She should absolutely pursue OF if she wants to and feels comfortable doing it, which she admitted to both. We've all seen the nude leak(nothing to worry about for her there) and her community won't allow her to fail. She already has members lining up for her OF. She could essentially be her Mary character, but IRL.
Though I do wonder if her relationship with another streamer is affecting her decision. Last time she checked OF was 6/16 and she hasn't really given an update about OF since the initial rejection.
