This is a fair point, and I do plan on addressing that mainly in the final post of this series of responses when I talk about the future of Weight Gaming and I hope a bit in my AI centric post which I am aiming to have released next week.
Due to how complex that topic a lone is this post is just addressing the voting itself as well as setting some ground work for the future responses.
That all being said your comment about “explicitly disallowing attacks on games for using AI” I think is a good point showing one of the areas we have faltered in. Our rules already prohibit such attacks like the ones against Second Helpings as you pointed out. In my eyes most of those have been us not being able to respond to moderation issues fast enough to prevent such escalation (which was also the case with second helpings). That is solely on us and is a failure on our side when it comes to moderating the site.
Once again I will get a bit more into it in my 5th post but while I wont ever ban what could be reasonable criticism I have been heavily considering us being more aggressive in the enforcement of our current rules instead of how laissez-faire we have operated up to this point.
