She is trying to become a Vtuber, that's what those support accounts are for.
Although she does mention that, with more support, she can afford more costumes, so more free pics or vids.
Both of her "paid" accounts do not have any extra lewd content, compared to twitter.
There is one special service, however, that you can buy from her.
It's called "name tag photo". Not sure about the details, but it looks like she will hold a piece of paper with your ID and take a photo.
Cost around 70 usd.
She also posts on Weibo. Mostly the content is the same as what she posts on twitter.
Only found this one vid missing in the twitter vid rip.(No boobs though
