The problem, like in that previous case, is that "human subject research" is a pretty narrowly defined category. It is mostly meant to cover testing out drugs on human subjects, and stuff like that. Notably, there is plenty of unethical research that doesn't qualify. So when an IRB gets a proposal that amounts to "I'm going to send some emails/interact with some folks online" their reply is likely to be along them lines "not our problem", and it becomes the responsibility of the research to assess the ethics of what they're doing.

The IRB boards I've interacted with or seen peers go through included more than just drugs etc. A survey or interviewing people has always been included as human subject research by the boards. Depending on the specifics, surveys & interviews may be exempt from a full review of the human subjects process, but only after the IRB itself has made that designation. Basically a PI shouldn't be talking to a human as as part of their research without the IRB making a determination on it.

Anything related to food & drug testing is usually its own special category of review within the IRB, but it's not just meant-- and has never been meant-- to only deal with biomed research. The Belmont Report in 1979 that gave rise to the modern IRB explicitly addressed research with human subjects, not just biomedical research. Anyone in that field is aware of the extreme examples like Milgram's work and the Stanford Prison experiment that make this review necessary.

It may be the case that some IRB's don't take that side of thing as seriously as they should, but that doesn't mean the ethical burden is primarily on the researchers. The legal liability is on the institution, and the IRB is the regulation-mandated body required to ensure compliance.

But when the Sokal squared hoaxers were submitting fake papers to humanities journals, it was deemed human subject research and widely denounced (by humanities researchers) for lack of ethical review. This seems to be a very analogous situation.
