If I was to guess generally what is happening, what we are seeing is a result of the new Google & Reddit partnership:

Google wants clean data from Reddit to train it's AI models "
Reddit plays a unique role on the open internet as a large platform with an incredible breadth of authentic, human conversations and experiences".
So Google needs "
authentic, human conversations", data from Reddit to train its models on.
Spam comments and comments with manipulated upvotes are the opposite of this.
Problem is Reddit relies heavily on human moderators to keep the data clean, which is inefficient. So in steps Google to lend a hand with their sizeable expertise in the area:
"
we’re pleased to announce a new Cloud partnership that enables Reddit to integrate new AI-powered capabilities using Vertex AI. Reddit intends to use Vertex AI to enhance search and other capabilities on the Reddit platform."
The "
other capabilities" is likely everything we have started seeing the last week. My guess is Google sent a team of machine learning engineers, data scientists and others over to Reddit months ago with the goal of ensuring Reddit data is cleaned up.
Google benefits by having clean data to train it's AI models. Reddit benefits by having less spam, providing a better experience for users, which is ideal for a company that is about to IPO. Investors love stories of huge percentage reductions in spam.
People who are just trying to make a buck by sharing & upvoting links on Reddit are unfortunately the losers.
