It started out noxious enough. The most on-the-nose offensive content shooting to the top day in day out. Most people got tired of it at that point, but a small few continued disliking content as it dripped in. They weren’t even enthusiasts, rather a fairly average group of users, and the diverse set of tastes that comes with that.
It took some time, but the lowest-rated content changed from raw gore to dissenting opinions to people trying to out-do each other in a game of hate-me-too. They would write about the things they did today, or were planning to do tomorrow. Outsider content was no longer detestable enough, you had to generate something yourself.
The platform got in the news, police got involved, admins took it down. But if a site ever allows you to sort by most disliked, give it a go, who knows what you may find.
