My comments are included in the piece - which you read in full here.
But here's a link to the blog post I wrote on the subject when the idea was first floated.
"You have to ask how they expect the Advertising Standards Authority (ASA) to police this?
And more importantly, why they think they are better placed to police this than those they seek to protect?
It's another example of the advertising world attempting to place a broadcast, centre-out solution on a peer-to-peer space. You ain't in Kansas any more, Dorothy.
They make the assumption that the act of setting up a page or account and filling it with dishonesty is equal to broadcasting that dishonesty to unsuspecting audiences. Which is to fundamentally misunderstand how distribution happens in social media."
