Suspiciously absent from the list of takedowns is anything on Reddit. Given the amount of obviously-chatGPT puppets on there, I'm somewhat 'surprised'.
Also a good reminder that if you're using ChatGPT for anything, they can and will examine the traffic and contents of your messages / replies.
I wonder if in the future they may offer a "service" to content providers. Say you're a reddit / forum / etc. You get supplied an API that you can run queries through that match any content that may have been generated through their service. You can then tag those accounts as bots. Of course, such an API will have costs associated with it...
