If you follow the link at the end of my comment, you'll be flagged as an LLM.
You could put this in an img tag on a forum or similar and cause mischief.

If you do follow that link, you can just clear cookies for the site to be unblocked.

Maybe not such a great idea since you don't control your links.
Reminds me of the time one of the homies made an image signature footer that was hosted on his own domain, would crawl a thread, and figure out your IP based on the "who is reading this" section of the thread.
You can also ignore requests with cross-origin referrers. Most LLM crawlers set the Referer header to a URL in the same origin. Any other origin should be treated as an attempted CSRF.
These refinements will probably go a long way toward reducing unintended side effects.
A bunch of CSRF/nonce stuff could apply if it were a POST instead...
It may be more-effective to make the link unique and temporary, expiring fast enough that "hey, click this" is limited in its effectiveness. That might reduce true-positive detections of a bot that delays its access though.
You could use a URL shortener to bypass the ban, but then you'll be caught by the cross-origin referrer check.
You also have not used <p hidden> to conceal the paragraph with the link from human eyes.
Moreover, there is no easy way to distinguish such a fetch from one generated by the bad actors that this is intended against.
When the bots follow the trampoline page's link to the honeypot, they will
- not necessarily fetch it soon afterward;
- not necessarily fetch it from the same IP address;
- not necessarily supply the trampoline page as the Referer.
Therefore you must assume that out-of-the-blue fetches of the honeypot page from a previously unseen IP address must be bad actors.
I've mostly given up on honeypotting and banning schemes on my webserver. A lot of attacks I see are single fetches of one page out of the blue from a random address that never appears again (making it pointless to ban them).
Pages are protected by having to obtain a cookie from answering a skill testing question.
Back then, legitimate search engines wouldn’t want to scrape things that would just make their search results less relevant with garbage data anyways, so by and large they would honor robots.txt and not overwhelm upstream servers. Bad actors existed, of course, but were very rarely backed by companies valued in the billions of dollars.
People training foundation models now have no such constraints or qualms - they need as many human-written sentences as possible, regardless of the context in which they are extracted. That’s coupled with a broader familiarity with ubiquitous residential proxy providers that can tunnel traffic through consumer connections worldwide. That’s an entirely different social contract, one we are still navigating.
I wouldn't be surprised if it was the same with LLMs. Millions of workers allocated dynamically on AWS, with varying IPs.
In my specific case, as I was dealing with browser-initiated traffic, I wrote a Firefox add-on instead. No such shortcut for web servers, though.
Your DNS mostly passes lookup requests but during homework time, when there's a request for the ip for "www.youtube.com" it returns the ip of your choice instead of the actual one. The domain's TTL is 5 minutes.
Or don't, technical solutions to social problems are of limited value.
And technical bandaids to hyperactivity, however imperfect, are damn useful.
I've deployed the same one for me, but setup for Reddit during work hours.
Both of us know how to get around the add-on. It's not particularly hard. But since Firefox is the primary browser for both of us, it does the trick.
I'm not affiliated with them, but it has helped me when I really need to focus.
Are these botnets? Are AI companies mass-funding criminal malware companies?
Without a doubt some of them are botnets. AI companies got their initial foothold by violating copyright en masse with pirated textbook dumps for training data, and whatnot. Why should they suddenly develop scruples now?
edit: ah yes another person above mentioned VPN's thats a good possibility, also another vector is users on mobile can sell their extra data that they dont use to 3rd parties. probably many more ways to acquire endpoints.

The trap in the article has a link. Bots are instructed not to follow the link. The link is normally invisible to humans. A client that visits the link is probably therefore a poorly behaved bot.
1. Their number: every other company and the mangy mutt that is its mascot is scraping for LLMs at the moment, so you get hit by them far more than you get hit by search engine bots and similar. This makes them harder to block too, because even ignoring tricks like using botnets to spread requests over many source addresses (potentially the residential connections of unwitting users infected by malware) the share number coming from so many places, new places all the time, means you can not maintain a practical blocklist of source addresses. The number of scrapers out there means that small sites can be easily swamped, much like when HN, slashdot, or a popular reddit subsection, links to a site, and it gets “hugged to death” by a sudden glut of individual people who are interested.
2. Use of the information: Search engines actually provide something back: sending people to your site. Useful if that is desirable which in many cases it is. LLMs don't tend to do that though: by the very nature of LLMs very few results from them come with any indication of the source of the data they use for their guesswork. They scrape, they take, they give nothing back. Search engines had a vested interest in your site surviving as they don't want to hand out dead links, those scraping for LLMs have no such requirement because they can still summarise your work from what is effectively cached within their model. This isn't unique to LLMs, go back a few years to the pre-LLM days and you will find several significant legal cases about search engines offering summaries of the information found instead of just sending people to the site where the information is.
3. Ignoring rules: Because so many sites are attempting to block scrapers now, usually at a minimum using accepted methods to discourage it (robots.txt, nofollow attributes, etc.), these signals are just ignored. Sometimes this is malicious with people running the scrapers simply not caring despite knowing the problem they could create, sometimes it is like the spam problem in mail: each scraper thinks it'll be fine because it is only them, with each of the many also thinking the same thing… With people as big as Meta openly defending piracy as just fine for the purposes of LLM training, others see that as a declaration of open season. Those that are malicious or at least amoral (most of them) don't care. Once they have scraped your data they have, as mentioned above, no vested interest in whether your site lives or dies (either by withing away from lack of attention or falling over under their load to never be brought back up), in fact they might have incentive to want your site dead: it would no longer compete with the LLM as a source of information.
No one of these is the problem, but together they are a significant problem.
Actual LLM involvement as the requesting user-agent is vanishingly small. It's the same problem as ever: corporations, their profit motive during $hypecycle coupled with access to capital for IT resources, and the protection of the abusers via the company's abstraction away of legal liability for their behavior.
"AI" is eating its own slop, and that is a problem:

They are trying to block automated LLM scraping, which at least has some possibility of having some success.
And I say this as someone who built a search engine with no AI: I know my audience for that service is very niche, with the vast majority of people using AI search because it's more convenient.
There's no cookies disabled error handling on the site, so the page just infinitely reloads in such cases (Cloudflare's check for comparison informs the user cookies are required—even if JS is also disabled).
If the site author reads this: make an exception for https://www.owl.is/blogg/index.xml
This is a common mistake and the author is in good company. Science.org once blocked all of their hosted blogs' feeds for 3 months when they deployed a default cloudflare setup across all their sites.
Unfortunately "mass scraping the internet for training data" and an "LLM powered user agent" get lumped together too much as "AI Crawlers". The user agent shouldn't actually be crawling.
How does this make you any different than the bad faith LLM actors they are trying to block?
This is not banning you for following <h1><a>Today's Weather</a></h1>
If you are a robot that's so poorly coded that it is following links it clearly shouldn't that's are explicitly numerated as not to be followed, that's a problem. From an operator's perspective, how is this different than a case you described.
If a googler kicked off the googlebot manually from a session every morning, should they not respect robots.txt either?
They get lumped together because they're more or less indistinguishable and cause similar problems: server load spikes, increased bandwidth, increased AWS bill ... with no discernible benefit for the server operator such as increased user engagement or ad revenue.
Now all automated requests are considered guilty until proven innocent. If you want your agent to be allowed, it's on you to prove that you're different. Maybe start by slowing down your agent so that it doesn't make requests any faster than the average human visitor would.
Sure, a bad site could use this to screw with people, but bad sites have done that since forever in various ways. But if this technique helps against malicious crawlers, I think it's fair. The only downside I can see is that Google might mark you as a malware site. But again, they should be obeying robots.txt.
The line gets blurrier with things like OAI's Atlas browser. It's just re-skinned Chromium that's a regular browser, but you can ask an LLM about the content of the page you just navigated to. The decision to use an LLM on that page is made after the page load. Doing the same thing but without rendering the page doesn't seem meaningfully different.
In general robots.txt is for headless automated crawlers fetching many pages, not software performing a specific request for a user. If there's 1:1 mapping between a user's request and a page load, then it's not a robot. An LLM powered user agent (browser) wouldn't follow invisible links, or any links, because it's not crawling.
The significant difference isn't in whether a robot is doing the actions for you or not, it's whether the robot is a user agent for a human or not.
