When researching, basically your success as an influencer had to do pretty much solely on your looks (or your photoshop skills) rather than your message. (for both men and women). You can be a 'vegan' influencer or a 'I eat meat still dripping in blood' influencer, and the most important 'variable' on your success was how attractive you were.
(outliers existed, but mostly they were 'connected/endorsed' by some big brand or celebrity already)
Tangentially, I've always been fascinated by anti-consumerist lifestyle design, and a little envious of people who have that natural earthy style to them, who appear cool without a lot of effort.
Then I read an article about Instagram influencers in some surfing town in Australia and saw how much their "anti-consumerist" lifestyle cost: long story short, looking poor is extremely expensive and it turns out they were married to corporate VPs who were able to work remotely and fund that kind of lifestyle.
It actually made me feel much better about my life. Now I'm convinced that actual anti-consumerism is frumpy, and I'm happy with that.
If you want to meet real anti-consumerists, they're not on the internet extolling their lifestyle. (yes, I know, no-true-scotsman and what-not).
They're busy surviving. Because they tend to be subsistence farming or very near to that. They may sell art at local fairs, or goods at local produce stands. But mostly they spend their time just trying to get by.
It's just like the 'homesteading' and 'van-living' movements. The people who are actually living those lives, and who aren't just doing it for validation on the internet aren't posting updates daily about their cute new milk goats or whatever, because they're super busy not dying and just trying to get by.

However, there's the class of bloggers who advocate for being middle-class frugal, saving up as much money as you want, and doing whatever you want with the rest of your life. Maybe some of them are full of crap but I believe many of them actually are practicing what they preach.
And there have been countless middle class professionals who've done basically the same thing without writing blogs about it -- they've just quietly lived their lives.
That lifestyle appeals to me. It just seems so much simpler and more efficient.
In the end, the influencer is depicted (accurately) as a victim of the protagonist's mental instability and manipulation, but it's her vapidity and inability to genuinely relate to anyone that made that victimization possible. She's as damaged as Ingrid is, just in a more subtle, socially acceptable way.
I didn't read class in the film quite the same way, but that's an interesting lens. I should watch it again.
