What the parent is suggesting is that content from forums is the only place where the model would have encountered the concept of getting a tip for a good answer. For all the other content in the training set like websites, books, articles and so on, that concept is completely foreign.

This is a first principles sanity check - very good to have against much of the snake oil in prompt engineering.

The one thing that is conceivable to me is that the model might have picked up on the more general concept, but if there has been a clear incentive then the effort to find a good answer is usually higher. This abstract form, I imagine, the model may have encountered not only in internet forums, but also in articles, books, and so on.
