Instead of focusing on whether posts are generated by AI or not, the mods (and reporters) should evaluate them based on their usefulness. In other words, continue what they have been doing since ever. Attempting to combat AI-generated content is a futile effort - its use will continue to grow and it will be used by almost everyone in the near future. Resisting AI feels like fighting against electricity during the 1800s (Yes, people did that).
they aren't resisting AI-generated, they are trying to discourage people from using AI-generated content because it is important that the person who posted the information to share or to answer someone knows what he/she is talking about. It also encourages people to actually read and learn something about the topic or discussion that they are joining or part of.
