So assuming all this happened exactly as Zhang says: how big a deal is this really? We aren't talking about mobs of fake accounts creating false content; we're talking about a bunch of pages "liking" content by various politicians. It's analogous to the applause at a speech by a politician: does anyone really think, "Wow! Everyone is clapping; this person must have the best ideas!" Nobody could really believe that the number of likes on a politician's Facebook post is indicative of anything meaningful.

Sure, it's better to have what a person sees accurately reflect reality, but what she's talking about is insignificant. It's a thumbs-up icon with a number beside it.
