What is the difference between this and a moderator on Reddit manually deleting a post?
If a moderator deletes a post someone else can post it again. If you create an automatic rule to prevent that then it's algorithmic.
All this talk is very funny to me because it shows that most people here are too young. The algorithm exists because the establishment demanded it. I say establishment because I remember what the old geek culture was and the demand didn't come from it. It came from outside of technical libertarian circle. Once social media companies said it is possible the demand became even more shrill and it culminated in 2016 when Trump won. The algorithm was created specifically to do what Zuckerberg made it do in 2020.
