Why did wisdom of the crowds fail?

Wisdom of the crowds summarizes the opinions of many people to produce useful results. Wisdom of the crowds algorithms -- like rankers, recommenders, and trending algorithms -- usefully do this at massive scale.

But several years ago, wisdom of the crowds on the internet started failing. Algorithms started recommending misinformation, scams, and disinformation. What happened?

Let's think about it in more detail. What changed that caused problems for wisdom of the crowds? Why did it change? What can we can we do about it?

Importantly, did anyone find ways to mitigate the problems? If some did fix their algorithms from amplifying misinformation on their platforms, how did they do that? And why didn't everyone fix their wisdom of the crowd algorithms to prevent them from amplifying misinformation?

I have my own answers to these questions, but I'm curious to hear others. If you have thoughts, I'm most curious to hear about whether you think anyone (at least partially) addressed the problems aggravating misinformation on the internet and, if so, why you think others have not.

my first reaction is that it stops being wisdom of the crowd when people know there is an algorithm which they can manipulate and profit from. Would be interested in your thoughts... but I guess that would come in the form of a book you are writing? I think one thing that would help is verified identifities and insuring a single vote / individual.
