> Have you considered, that the AI is simply trying to greedily close the points on it's knowledge graph?
No, all I've thought is that the AI sucks and is broken and for a company that's supposed to have the smartest people and unlimited money it should know better.
Perhaps having a dense graph is simply more profitable for FB?
Sure they won't know who you know, but they can send their messages (ostensibly "on behalf of") that person you know/friended.
Sure, poison your personal data (get your Fakebook on), but going out and spamming connections may not exactly hurt FB.
