- Filtering and reporting posts according to the length of post
In as much as one line posts could also be quality, we know that majority one line posts are spam. So, reporting all one line posts to the moderators by the AI will be of great help. In the same manner unduly long posts will be checked of repetitions and reported to the moderators who inturn decide whether such short or long posts are good.
AI-generated posts are lengthy, not short.
AI spammers make very lengthy posts, not short ones and you even don't need to use AI detective tools to guess that a post is created by AI tool. Of course, to confirm, you need to use not only one but some AI detective tools.
