What is surprising is your assumption Facebook isn't aware of this. Nay, that Facebook was not designed for this very purpose. Facebook, who employs some of the top data analysts and AI specialists, actively building tooling on the cutting edge of those fields, who's funded primarily by commercial use of its platform, with the for-pay 'reach' being the most obvious monetization scheme.

I don't see how you could be missing that everything about Facebook incentivizes nonsense such as like-factories.
