This seems unworkable. Gaining attention is intrinsically commercial activity. Attention has value; you can't stop it bleeding into the rest of the world. Some examples and questions:

- An "influencer" gets her photo on a Wheaties box. After that, the influencer doesn't have to do overt advertising to promote the cereal, their fortunes are bound together.

- In politics, as the former US president so amply demonstrated, attention is a currency.

- What about the exchange of ideas? Can one talk about the contents of a book without selling (or discouraging the sales of) the book?

- Is any mention of brand names to be prohibited? If you can mention a brand, unless all the brand's marketing has been completely ineffective, you are selling the brand. Don't like it? Pass the Kleenex.
