I think companies/people who are deep in google SEO have also infiltrated reddit. Still better than Google in some regards but only a matter of time before it is degraded beyond useful value.
I’ve been on the site since 2012 and it’s all I can see. There is a subreddit from around the same time I joined called HailCorporate documenting a lot of the obvious instances but I’ve noticed lately that most people have been trained to mimic the ads just by being on the site for a short time
Lately the most obvious example of what I mean is on the TV subreddit: shows aren’t just shows any more — they are almost always referred to as X on Y where Y is the network or streaming service the show is currently on. Sometimes it results in hilarity as in the case of a show called “You” with the show’s sub called YouOnLifetime - a network it is no longer available on.
A less cynical person would say that people are just trying to help people find the show they’re speaking of, but it ends up being a constant string of Corporate keywords in upvoted posts and wow, just happens to be great for SEO.
