1) New system comes out that indexes/controls/regulates a naively created dataset
2) Data consumers adopt that system and experience benefits
3) Data suppliers learn rules of system and take advantage of it to improve the positioning of their data, thus breaking the intent of a system built on the assumption of naive creation
4) Users complain about the broken system
5) New entrants realize that the original system actually solved the core problem really well, and there are no easy ways to solve the 'gaming the system' problem
6) Flawed system remains the best available option indefinitely
It's like entropy, there's just no fighting it.
EDIT: And to extend this beyond Google - do you see a lot of long text blocks in 7 second tik tok videos? That's because the creator found a way to game the algorithm.
