They can choose to count those in various ways. See the stories about Facebook exaggerating video engagement. Additionally Facebook has gladly allowed obviously fake and spammy accounts on the site for ages. Note also that nobody is claiming Facebook is a ghost town. Clearly a lot of people still use it.
