The API protest in 2023 took away tools from moderators. I noticed increased bot activity after that.
The IPO in 2024 means that they need to increase revenue to justify the stock price. So they allow even more bots to increase traffic which drives up ad revenue. I think they purposely make the search engine bad to encourage people to make more posts which increases page views and ad revenue. If it was easy to find an answer then they would get less money.
At this point I think reddit themselves are creating the bots. The posts and questions are so repetitive. I've unsubscribed to a bunch of subs because of this.
