Check out Daily Mail for example, where 1,000-7,000 down Trump approving arrows appear on the “best Rated” in minutes, hell seconds.
I love the DM comments section. It is one of the remaining places where people can up or down arrow a comment anonymously. Sort of a grassroots opinion monitor. Every day there are posts claiming the paper is “too liberal” or “too conservative”, depending on the article, the author, the point of view expressed or the “community” affected by or enthusiastic about the topic.
Naturally DM has filters and they remove many comments unfavorable to certain groups, but articulate posters often find a way to say what they mean in roundabout words, and then the up or down arrows flood in.
