However, if this catches on and becomes more prevalent (and I could see that happening), then I'd expect some kind of cyber-vandalism law to be enacted. They can't prosecute based on hacking, because it isn't. But it could be argued you're 'defacing/destroying' digital property by editing to add content that knowingly will mess with their algs. Sooner than that though will be an addition to the EULA, that users cannot enter AI generated content or they agree to get fined, or some such nastiness.
The Cyberpunk RPG came out in 1988, and I was in my early 20s. Each decade since I've marvelled at how much closer to that dystopian world we've gotten, and the slope of the downward slide increases every decade.
Why do I say that?
Because the image of Reddit that's been in my head until today is of an Open Source type thing started by Aaron Schwartz. He was a founder, but that is not today's Reddit. I did some cursory digging and found Reddit is primarily owned (majority shareholder) by Advance Publications, Inc. These are the same people who own, or majorly own (primary or major shareholder): Conde Nast and all its subsidiaries (which now owns Ars Technica), American City Business Journals, Charter Communications, Warner Bros. Discovery, the Ironman Triathlons, many newspapers, Turnitin.com, and probably more. In 2019 Advance Publications was named the largest privately owned American company.
