If you go by likes in posts (which is a terrible metric) in her "everything nice" tier, she´s made over 5300$ in October alone.
There's currently 592 paid subscribers, though at what tier is not publicly available.
Even at 5$ a month, the tier with no content, that's just under 3000$. If you move up to "spice", the first tier with content, that's just over 11000$. Monthly.
I very much doubt she's getting that much as a cachet for stand up shows, could be wrong tho, but at least there's no way she's getting it regularly. Plus on Patreon she doesn't have to come up with material for her jokes. On her charity post she mentions this year alone she donated 17450$.
Why do you think there's an epidemic of egirls now? It's literally free money, A LOT of free money.
