I agree with most commenters here that this crosses the line of ethical research, and I agree that the IRB dropped the ball on this.

However, zooming out a little, I think it's kind of useful to look at this as an example of the incentives at play for a regulatory bureaucracy. Comments bemoaning such bureaucracies are pretty common on HN (myself included!), with specific examples ranging from the huge timescale of public works construction in American cities to the FDA's slow approval of COVID vaccines. A common request is: can't these regulators be a little less conservative?

Well, this story is an example of why said regulators might avoid that -- one mistake here, and there are multiple people in this thread promising to email the UMN IRB and give them a piece of their mind. One mistake! And when one mistake gets punished with public opprobrium, it seems very rational to become conservative and reject anything close to borderline to avoid another mistake. And then we end up with the cautious bureaucracies that we like to complain about.

Now, in a nicer world, maybe those emails complaining to the IRB would be considered valid feedback for the people working there, but unfortunately it seems plausible that it's the kind of job where the only good feedback is no feedback.
