Can you spot the likely AI Bot Poster?

Context

Let's take this at face value. Hypothetically speaking, what would be the purpose for an AI bot (let's throw out spamming for this discussion)? Has AI bots come into a2k (for reasons other than spamming)? That can't be ruled out that if it hasn't happened before that it will happen sometime in the likely near future. If not just for further training for the AI bot in interactions with actual people.

Will an a2k registered/active member AI bot be from the generation of AI bots to pass the Turing Test?

As an aside? Neither Google nor Goodreads recognizes the book titles nor the alleged book authors (though one can argue that either book was self-published and not picked up by search engine or the book database).
