Not waging genocide on fit models as far as I can tell. Critiquing the bland predictability of advertising, including its use of fit models, and the demoralizing effects of a massive, relentless torrent of poorly-targeted ads you can't stop, yes.

There's nothing here that can't be hung on a pre-existing hook of "advertising sucks" (for many reasons including shallowness and sexism) and/or "Instagram sucks" (due to its being an ad platform masquerading as a "social" "sharing" "platform"). But you can also add the bluntness of their ad targeting algorithm to the list. It sucks. "She ordered yoga pants once... TURN THE YOGA FIREHOSE ON HER!"

I think everybody here including the author knows why she's seeing the ads. Likewise "They don't do a perfect job" and Facebook's non-omniscience, are pretty obvious too. But it's worse than doing an imperfect job; it's idiotic and self-defeating for both the ad broker (Facebook/Instagram) and the advertiser. She is never going to respond to any of those ads. Even less so, the more they make her feel like nothing more than a place where leggings and bras go, that has money in it. Though I guess neither the broker nor the advertiser cares about responses, only viewings.
