The AI bot assault, on the other hand, is one company (or a few companies) re-fetching the same data over and over again, constantly, in perpetuity, just in case it's changed, all so they can incorporate it into their training set and make money off of it while giving you zero credit and providing zero feedback.
The refrain here comes down not to "AI" but mostly to "the AI bot assault" which is a different thing. Sure lets have an discussion about badly behaved and overzealous web scrapers. As for credit, I've asked AI for it's references and gotten them. If my information is merely mushed into AI training model I'm not sure why I need credit. If you discuss this thread with your friends are you going to give me credit?
Yes. How else would I enable my friends to look it up for themselves?
Talented people that want to scrape or bot things are going to find ways to make that look human. If that comes in the form of tricking a physical iPhone by automatically driving the screen physically, so be it; many such cases already!
The techniques you need for preventing DDoS don't need to really differentiate that much between bots and people unless you're being distinctly targeted; Fail2Ban-style IP bans are still quite effective, and basic WAF functionality does a lot.
"Use a CDN" is not sufficient when these bots are so incredibly poorly behaved, because you're still paying for that CDN and this bad behavior is going to cost you a fortune in CDN costs (or cost the CDN a fortune instead, which is why Cloudflare is suggesting this).
