I think this is totally mistaken. An ad seller which also wants to respect privacy keeps this data in-house and does the ad targeting themselves. The advertiser never needs to see personal information for this kind of market to give people ads related to overheard conversations.
This could even be automated; LLMs can sentiment-analyze social media posts to surface ones that are critical of LLM outputs, then automatically extract features of the post to change things about the running model to improve similar results with no intervention.
I.e. human and mouse fat cells epigenetically change in response to weight gain*, they don't change back in response to weight loss, and in the mouse case they demonstrated that the mice with the changes gained the weight back faster.
I would (naively) expect this to also be true in humans, which would explain why rebound weight gain is incredibly common.
I personally see this as significant because it's evidence that obese people and formerly obese people are directly going to have more trouble getting thin, at the level of cell biology, than people who were always thin.
*The abstract implies this about human cells but doesn't explicitly say so. I presume it's a known fact about human fat cells.
That could also be a user login, maybe, with per-user rate limits. I expect that bot runners could find a way to break that, but at least it's extra engineering effort on their part, and they may not bother until enough sites force the issue.
The foundation of a computer science education is a rigorous understanding of what the steps of an algorithm mean. If the students don't develop that, then I don't think they're doing computer science anymore.
If the group's activity is easily visible and distinct from what everyone else is doing, it's not necessary.
