You should check out the 'Ultimate Bill Hicks' DVD available. Amazon have got it at reduced price at the moment and it is excellent. I laughed and laughed.
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.
Seemingly-genuine comments like that could be a plausible future step for escalation of advertising.
I'd guess there are people who would "rent" access to their active social media accounts to a company operating a bot capable of writing subtle "recommendation"-style comments. Sort of a merger of blog-comment-spam-bots and paid "influencer" posts.
heh, funny. But that's the point, deceiving is REALLY easy. But without trust and good faith, things start to get weird exponentially, it adds up. And so, as I saw in another article, truth becomes the roadkill.
