Just read it. It's a scary potential. It might start doing it automatically one day. If anyone discovers the bug it will be just "oh sorry, just an algorithm bug, we'll tweak it, we promise".

I never signed up for Facebook to start with, but I got a glimpse of this power with Netflix. The movie recommendations were so good that I end up liking them if took its advice. Where normally I wouldn't have watched them based on rating, synopsis, or title. I had realized some algorithm at Netflix seems to know me better than I knew myself. Then thought what if it suddenly decided to use that against me, because it somehow would be more profitable for it.
