I remember back in the day when the same shit was happening because websites would just put, like, an entire dictionary in tiny, hidden text somewhere at the bottom of the main page so it would have a greater chance of showing up no matter what you typed into the search engine.
It's pretty wild that they didn't think about people doing exactly the same thing with all the new methods they came up with to make searches "relevant" since that was one thing that made Google so much better than the competition back then.
Any system you make to push certain things over other things are going to be figured out and gamed.
that's the thing, in the past they had this problem try to solve it and fixed it, now they just cash out from ads campaigns and fuck you customer stop complaining and submit
