Let me start by saying that I am in favour of the rule. Going into topics-centered community and voicing against that topic is kind of stupid, and everybody should be able to feel safe in their own spaces. All my concerns (generality of the rule, downvote trolling and automating moderation) were already voiced by others and addressed one by one. Also, as a practical suggestion, maybe we can have sticky posts in each community where the rule will be applied? Not forever, but for a set period of time.
I waited longer to give my answer, as I am very skeptical about AI in general but in favour of many other instance topics, and I wanted to form my own opinion on the topic at hand before commenting. I am really happy at the level of the discussion here and how the feedback was received by OP. I didn't agree with some comments on other posts leading to this one, but I am happy to see that the discussion was kept objective and on-point, so a huge thank to OP and everyone who participated for showing me how the instance governance and discussion works (I'm relatively new here).
In the end, while I don't go specifically go searching for AI content and barely see it in my feed, I am happy that stuff like AI-horde exist, and I really think it's a good way of doing things. And in general, the governance experiment here and the way this instance is managed is way more important for me than my own opinions on AI.
I totally agree with you, thanks for suggesting this change.
