Post making contest 3.0

My fellow posters, we stand at an impasse. We have two posts that pass Rule 1; yet, it seems, they cannot be readily quoted or deconstructed to pass it again.

But we must not lose hope in these trying times. We must not forget that we have worked out the conditions for rules 2 and 5. Surely, with our best efforts, we can determine rules 3 and 4, and better prepare ourselves for the struggle to find rule 1.

We should consider what else we know - that rules 2 and 5 can be passed by a blank post, but 3 and 4 cannot. And yet! And yet, even a single letter will pass rules 3 and 4, regardless of its identity. From these humble clues, surely we can build the foundations of a new posting theory.

Persevere, posters of the Post Making Contest. With our combined efforts, surely we can pass all the rules. God bless you, and God bless the Post Baking Concert.
