It's not a random person doing something random though. It's bait leveraging two very hot brands (Fable! Harry Potter!) and gluing them together with the the most clichéed, of-the-moment ad copy prose style. I don't hate the project or the brands particularly, but you have to be living under a rock not to be aware that social media is absolutely awash in this sort of content.

You've always wondered what would happen if Thing You Like had existed alongside Other Thing You Like. They called you crazy. They told you it could never happen.

They were wrong.

For the first time, Thing and Other Thing together - just like you imagined. It's not fiction. It's not a dream. It's real, and you can have it now - today. Thing Other Thing. Experience the magic with 40% off your first month's subscription if you sign up in the next 20 minutes.

I don't feel as activated about it as OP, but only because I've already opted myself out of this media landscape as much as possible. I think it's perfectly natural to be hostile towards such overt hijacking of one's limbic system. Modern marketing is incredibly toxic.
