I can confirm this is not an ad, 'cause we didn't launch the campaign yet :)
It was published without any communication for now, just we had to publish it in advance for calendar reasons (our communication manager going on well deserved holidays, and the person taking over starting only Monday)
So you've cracked a secret that won't be a secret from the beginning of next week.
If you're interested, we can come back to HN as soon as we have launched the campaign to inform you, and answer any questions you may have.
It didn't seem to me that I should tag it as Show HN, but maybe I was wrong.
