It was only a matter of time, @nixCraft . For the record, I don't think deleting profiles, questions and answers will do anything more than hurt human beings, right now. It's too late. It was already too late before LLM bots became realistically applicable for this grift because the corporations already had the content.
We wrote that content – me too! – freely, willing to aid and help our human peers who suffered from the problems we sought to answer and we did it in the hope for a better www.
Unfortunately, we have not realised that better www and are instead seeing the growth of the saddest possible web.
But it shan't last. This is a bubble – wait for it to burst.
