Yep this! How can you really beat SEO when people can just try new things all day and see if it helps their rankings? I don't feel there's a solution here. Everyone suffers under SEO types just trying to bring scammy things to the top of the results page.
The thing is, I have a site in a very competitive niche that's full of black hat SEO tactics, and I am doing my white hat best hoping that Google tanks these sites when they update algos over time, and I'd then be the best placed to take their spots over.
