In my opinion, these companies should put their effort elsewhere. Obviously if all someone is doing on their platform is looking up how to build a nuke, where to buy uranium, the best city to explode it in, etc. please report them to the authorities. If someone is clearly just using LLMs to write hate speech they go post on the internet, ban them. And so on.
This cat & mouse game trying to have LLMs police inquiries is ridiculous to me.
