It was slightly over $400/hr. The claim it was $5k/hr comes from the Berkeley guy who didn't include all the time she spent in his calculation. He either misunderstood or intentionally lied to make her look bad.
I found this story absurd enough ($5k/hr?!) that I looked into it more and think the full story should be told:
- Her hourly rate is closer to $400/hr. The Berkeley guy said it was $5k/hr because he just took the total pay and divided by hours spent on one thing. But she spent hours on some other things too that he didn't included in the denominator.
- He originally tweeted her address and other harassing things, which is against Twitter's rules. That tweet was reported and taken down.
- Stanford has threat prevention staff that alerted her to his tweets and also alerted the authorities, as is apparently their policy when people are tweeting harassing stuff about their faculty. She never personally reported him to the police. I wouldn't fault her if she did though.
- It's clearly not racially motivated.
- Despite all that, she tweeted an apology to appease the mob.
- Finally, I don't like either of them. He is a harassing doofus who is trying to make her seem racist. She is trying to dumb down math for California students in the name of equity. He's worse but I don't really like her either.
