That's not an ad, that's genuine interaction. The poster is not an actor(or someone trying to act a role), not an algorythm, not a corporation, not a marketer or salesperson. We must learn to discern between stuff if we want to consider ourselves "real-worlders" or whatever. If you get the concepts mixed up in your mind then your discernment gets distorted and you start conflating what's authentic and what's artificial. That's why it shits in your head.
