Yeah, it sucks. But we do need to keep in mind now that social media psy-ops (or whatever the spooks are calling it) have become significant -- just as Amazon user reviews have gotten way more polluted, but without the direct personal feedback you get from buying the wrong item.

There was a recent story about an academic study of the methods of in-China Party shills (I forget the link). By my skim they were more about distraction and noise than obvious pushing of the party line.
