I don't know about 'advertising', but Bahai don't allow campaigning when running for leadership position. I would imagine it would be some where along line of that. It encourage action speakers louder than words.

With all the modern techniques (used by neurosciences) in the modern advertising is pretty all entrainment and brain washing at this point any way. So no harm in making all that illegal. I'm pretty ok with a world with no advertising, and just function by word of mouth and network of trust.
