That is a very good question and one that really cannot be provided a simple yes or no answer. When this was done originally, it was not an official experiment done for research purposes per se. The newer ones most possibly are, but it may not be an experiment in the traditional sense.
Guidelines usually imply informed consent as well as the fact that no harm will be done. It is difficult to say whether or not any psychological harm was committed in the current experiments with adults. I am sure there are instances of trauma because if you see some of her videos you will definitely view examples of turmoil where it appears that someone is being harmed.
Many of the experiments through recent history have violated ethical standards: The Stanford Experiment; many of Skinner's shock experiments and of course things like the Tuskegee airman.
I have an article on some of those too: https://soapboxie.com/government/Some-of-the-Most-...
I cannot give you an honest answer, but you bring up a good point. Most universities have IRB (Institutional Review Boards) that approve experiments now. Please see https://www.apa.org/ethics/code/ for the APA Code of Ethics.
