The repost bots often use oddly-phrased headlines -- often commenters will even talk about how weird the headline is. I can’t tell if the posters are actually bots, or if they are content farmers from certain countries. (The odd phrasing may sound natural in their language.)
Another tactic is to post an obviously incorrect headline to draw engagement, like mis-identifying a picture of the Empire State Building as Chicago.
Both of these happen frequently with image posts.
