I am sure we already have and will have even more shitposters who use AI-generated content in the future. I don't like seeing it, and it's plagiarism. Cheap merits and ranking up are the reasons people will use it. Thus, it's cheating. It's not always going to be easy to differentiate someone with excellent English skills and a person who uses AI bots.
I don't think using AI generator is plagiarism, but if the AI generator took someone text, then it's good since some people can report it to make these shitposters get banned.
I think any user especially merit source need to give merit to a post which have an emotion and a subject. Usually AI generated post are objective and only discuss about the particular matter. Although there are few users are tend to explain particular thing in very objective.
