Advertising Phore itself definitely wouldn't be allowed. That's why I initially rejected their bids in the auction. Phore is definitely an "ICO-type-thing", which is explicitly banned from advertising: buying these sorts of tokens is something like buying shares in penny stocks, but even far more risky. However, I interpret this ad as advertising a product of Phore, namely the Graphene ecosystem and apps built on top of it such as their Marketplace. By analogy, I see this like Nikola advertising their fuel cell technology and their maybe-soon-to-be-available vehicles, not Nikola advertising NKLA shares.
