Just check it yourself, this is something that needs to be fixed. I am not against what you do but to be honest, an AI can do nothing in this case. One positive thing it can bring is to report some nonsense posts or threads to moderators.
Using AI to automatically flag / report spam / nonsense threads and posts does seem like a useful application of this technology. It would need to be a somewhat purpose-built AI though, trained on actual Bitcointalk data. Not as easy as 'throw it into ChatGPT on it', sadly, but probably much more effective.
