Adding to some speculation:
I WAS a long time supporter, even before her debut phase of the V-Tuber model she was planning to use long term and make content with. This was like 2 years ago.
Her old Patreon had lewd stuff of the V-Tuber and this is where the lewd audios began. Slowly she would also then post SFW pics as an immersion break every now and then. She realized that people really ate it up and started posting riskier ones. I believe in the early days she also had a BF and would sometimes talk about him during her normal talking audios. At some point they weren’t together anymore and I did notice a shift in riskier content.
Anyway fast forwarding a bit, she started posting full nipple and pussy shots with her face out of frame but would delete these pics 1-7 days later. Sometimes it’d be in the form of a google drive link with an expiration. This always irked me. The highest tier promised these spicy pics and then she announced dialing back on the spicy content. She also stealth edited the tier description. My guess is for two reasons, she now has a roommate after moving across State lines and I speculate she’s seeing someone else.
With the spicy pics mostly gone, she did create a new tier for the custom letters. I was unsubbed at this point because I was paying $30/month for literally nothing. She had a dry spell for a 3 month period where she posted nothing; only audio voiceovers that would get posted on Twitter a day later or often hours later.
So I stopped paying attention to her and looks like she kinda went back in the spicy pics stance. I guess she realized the money was too good and I cited that reason for my Patreon cancellation. However it’s not to the same caliber as before; still scraps IMO. As far as I know, this gig and her part time coffee shop job are her main sources of income
