I only just now heard about the AI bot persuasion experiment carried out on Reddit users on the r/ChangeMyView subreddit.
This is the post in which the CMV mods let users know that they were experimented on without their knowledge: https://www.reddit.com/r/changemyview/comments/1k8b2hj/meta_unauthorized_experiment_on_cmv_involving/

What do our #aoir #ethics people think about this?

@nik Well, difficult to avoid in Swiss academia these days, as many are learning about ethical oversight laws, structures and processes 😬

And I think I’ve also seen @cfiesler and @michaelzimmer posting.
