I'm pretty sure there was a lot of human posts, but I could pretty much see a bunch of claude-being-claude in there too. (Claude is my most used model).

I bet others can recognize the tells of some of the other models too.

Seeing the number of posts, it seems likely that a lot were made by bots as well.

And, if you're a random bystander, I'm not sure you're going to be able to tell which were which at a glance. :-P
