Fairly sure they're referring to situations like the following: re Ariana Grande, posted at least 5 times in the last 24 hours re Clown on escalator, at least 5 times in last 24 hours re Bullshit Tinder letter and response, at least 5 times in the last 24 hours Those are just off the top of my head. The shit is annoying. Just because a  post was good once doesn't mean I want to see a half dozen iterations of it on the "new" page. Edit: I spell like shit when I first wake up, apparently.
