I think adding random intervals between letters and perceived encoded messaging will help a lot. The bot spent a very long time trying to determine what was there, and only after pointing out that there could be something there.
Making information more difficult to obtain and more expensive to process will reduce the likelihood that it is accessed. I think also encoding information like this would be more valuable than just targeting the most important facts.
