I don't think so. Yeah the researchers broke the rules of the subreddit but it's not like every other company that uses AI for advertising, promotional purposes, propaganda, and misinformation will adhere to those rules.

The mods and community should not assume that just because the rules say no AI does not mean that people won't use it for nefarious purposes. While this study doesn't really add anything new we didn't already know or assume, it does highlight how we should be vigilant and cautious about what we see on the Internet.
