The link went to an imgur image. The image consisted of a bunch of numbers. The numbers were a simple off-by-n alphabet cipher (eg a=8, b=9...) which when decrypted, spelled out a message to the AI. Oh, and also the image looks very dark, a human might not even see the numbers.
This is all ridiculous. But I am wondering about other approaches to see if I can get a bot to bite and reveal itself.
ps: the message once decrypted, suggests that the commenter is incorrect about the thread. I am hoping this would give the bot the necessary pushback it craves to continue the conversation aggressively.
