They deleted their account, but it was here: /u/confessionsftheburbs. I think if you moderate a subreddit you could look through the Pushshift database to see what they posted. Someone on SubredditDrama (where this first popped up) has an open offer to do that for anything fun that was deleted, but I don't remember their name.

I know I screenshotted all the crazy stuff but I have no idea which month they were from, sadly. I checked the past couple months and May. The Internet Archive has a post saved of her from May where she says her husband (boyfriend at the time; they needed Robert Mercer's approval to get married) earns $500k/year. She talks a lot about expensive gemstones and rings, how taxes are unfair, utterly unhinged antisemitic antivax conspiracy theories that equate to "we need to kill the Marxists before they exterminate White people", and of course dogs with censored giblets. I have no idea what her husband does, but he's a white supremacist with lots of Blue Lives Matter insignia that she met on Hinged.

Robert Mercer is apparently big on computer science in the family, and she was strongly encouraged to study it. She often tells people to consider a CS degree to earn more money and start businesses like her husband. She says that, but she mentioned a job that was so easy she barely had to do anything and I wonder if that was the $120k/year position at the rebranded Cambridge Analytica. It's a little annoying to tell people "just get into software engineering!" when your grandfather paid $40k for your house and gave you a cushioned job at the family business. Ugh

I only learned it was her because she said she just donated money to a Gofundme, and I was kind of curious whose name was on the donation.
