Coordinated Inauthentic Behavior. Lol! From the title I thought it was about some online flashmob where people look at unusual stuff for a day to pollute Facebook’s targeting data.
"Looking at unusual stuff for a day" sounds like authentic action to me. People often do weird things. "Inauthentic action" is a pretty common term to refer to times when people use tools to make something look more popular than it is by faking action - it's inauthentic because an event which should reflect an action (i.e. computer activity which should be triggered by direct human action) doesn't (i.e. it is computer activity which wasn't triggered by direct human action, so it's not an authentic action).
