alt Hacker NewsThe bot situation on the internet is worse than you could imagine
Comments
Knew it was getting bad, but Meta's facebookexternalhit bot changed their behavior recently.
In addition to pulling responses with huge amplification (40x, at least, for posting a single Facebook post to an empty audience), it's sending us traffic with fbclids in the mix. No idea why.
They're also sending tons of masked traffic from their ASN (and EC2), with a fully deceptive UserAgent.
The weirdest part though is that it's scraping mobile-app APIs associated with the site in high volume. We see a ton of other AI-training focused crawlers do this, but was surprised to see the sudden change in behavior on facebookexternalhit ... happened in the last week or so.
Everyone is nuts these days. Got DoSed by Amazonbot this month too. They refuse to tell me what happened, citing the competitive environment.
I’ve been sitting on this page for two minutes and it’s still not sure whether I’m a bot lol. What did I do in a past life to deserve this :(
I'm surprised at the effectiveness of simple PoW to stop practically all activity.
I'll implement Anubis at low difficulty for all my projects and leave a decent llms.txt referenced in my sitemap and robots.txt so LLMs can still get relevant data for my site while.keeping bad bots out. I'm getting thousands of requests from China that have really increased costs, glad it seems the fix is rather easy.
> These bots are almost certainly scraping data for AI training; normal bad actors don't have funding for millions of unique IPs thrown at a page. They probably belong to several different companies. Perhaps they sell their scraped data to AI companies, or they are AI companies themselves. We can't tell, but we can guess since there aren't all that many large AI corporations out there.
Is the theory here that OpenAI, Anthropic, Gemini, xAI, Qwen, Z.ai etc are all either running bad scrapers via domestic proxies in Indonesia, or are buying data from companies that run those scrapers?
I want to know for sure. Who is paying for this activity? What does the marketplace for scraped data look like?
> Before it was enabled, it was getting several hundred-thousand requests each day. As soon as Anubis became active in there, it decreased to about 11 requests after 24 hours
I love experimental data like this. So much better than gut reaction that was spammed when anubis was just introduced
On my computer, with Firefox it uses 14 CPU cores, consumes an extra 35 Watts, and the progress bar barely moves. Is this site mining cryptocurrency?
On Safari or Orion it is merely extremely slow to load.
I definitely wouldn't use any of this on a site that you don't want delisted for cryptojacking.
I'm getting this patern a lot on Prestashop websites, where thousand, to not say hundreds of thousand, of request are coming from bots not announcing themselves in the User-agent, and coming from different IP's
Very annoying. And you can't filter them because they look like legitimate trafic.
On a page with differents options (such as color, size, etc...) they'll try all the combinaisons, eating all the ressources.
Is Anubus being set to difficulty 8 on this page supposed to be a joke? I gave up after about 20 seconds.
> The IPs of these bots here actually do not come from datacenters or VPNs most of the time; the overwhelming majority come from residential and mobile networks.
So I started searching for what these residential proxy networks actually are.

We started building out a set of spam/fraud/bot management tooling. If you have any decent infrastructure in place already, this is a pretty manageable task with a mismash of techniques. ASN based blocking (ip lookup databases can be self hosted and contain ASN) for the obvious ones like alibaba etc, subnet blocking for the less obvious (see pattern, block subnet, alleviates but doesn't solve problems).
If you have a logging stack, you can easily find crawler/bot patterns, then flag candidate IP subnets for blocking.
It's definitely whackamole though. We are experimenting with blocking based on risk databases, which run between $2k and $10k a year depending on provider. These map IP ranges to booleans like is_vpn, is_tor, etc, and also contain ASN information. Slightly suspicious crawling behavior or keyword flagging combined with a hit in that DB, and you have a high confidence block.
All this stuff is now easy to homeroll with claude. Before it would have been a major PITA.
> safari can't open the page
What is the point of these anti bot measures if organic HN traffic can nuke your site regardless? If this is about protecting information from being acquired by undesirable parties, then this site is currently operating in the most ideal way possible.
The information will eventually be ripped out. You cannot defeat an army with direct access to TSMC's wafer start budget and Microsoft's cloud infrastructure. I would find a different hill to die on. This is exactly like the cookie banners. No one is winning anything here. Publishing information to the public internet is a binary decision. If you need to control access, you do what Netflix and countless others have done. You can't have it both ways.
> let webWorkerURL = `${options.basePrefix}/.within.website/x/cmd/anubis/static/js/worker/sha256-${workerMethod}.mjs?cacheBuster=${options.version}`;
It looks like it's computing sha256 hashes. Such an ASIC friendly PoW has the downside that someone with ASICs would be able to either overwhelm the site or drive up the difficulty so high that CPUs can never get through.
Hugged to death?

So the elephant in the room: How much of HN is bot generated? Those who know have every incentive not to share and those who don't have no way to figure it out. At this point i have to assume that every new account is a bot
Looks like they've gone ahead and implemented the easiest fool-proof method of preventing scraping as the site is currently not loading across mutliple devices.
Not even a 404, just not available at all.
Not sure what they are doing, but they don't seem to do it well.
You can build some great anti-bot mechanisms with simple https://github.com/abrahamjuliot/creepjs logic. A normal user will often appear 31% or lower 'like headless score', mobile is a bit different. You'll still have trouble against sophisticated infra: https://x.com/_alexspring/status/2037968450753335617
An interesting and sad aspect of the war on bots and scraping that is being waged is that we are hurting ourselves in the process, too. Many tasks I'm trying to get my AI assistant to do cannot be done quickly, because sites defensively prohibit access to their content. I'm not scraping: it's my agent trying to fetch a page or two to perform a task for me (such as check pricing or availability).
We need a better solution.
Maybe my imagination is just too accurate but this didn't tell me anything I didn't expect to hear.
> Here is a massive log file for some activity in the Data Export tar pit:
A bit of a privacy faux pas, no? Some visitors may be legitimate.
Looks like Anubis is also blocking robots.txt which seems to defeat the point of having robots.txt in the first place.
Worse than I could imagine? I imagine that bots might destroy the internet. Not just the internet as we know it; I mean make the internet completely unusable to any human being.
I don't know if they have issue with my ff+ubo, but it is almost a minute that anubis is blocking me. screw them.
As soon as I see that anime bot thing which this website is using I close the tab. More annoying than Cloudflare.
At first glance this seems like a crypto miner.
Maybe I’m a bot, I gave up waiting before the progress bar was even 1% done.
>How can you protect your sites from these bots?
JA4 fingerprinting works decently for the residential proxies.
My grad school research was on computational models of human/machine cognition, and I'm now commercializing it as a 'proof-of-human API' for bot detection, spam reduction, and identity verification.
One of the mistakes people assume is that AI capability means humanness. If you know exactly where to look, you can start to identify differences between improving frontier models and human cognition.
One concrete example from a forthcoming blog post of mine:
[begin]
In fact, CAPTCHAs can still be effective if you know where to look.
We ran 75 trials -- 388 total attempts -- benchmarking three frontier AI agents against reCAPTCHA v2 image challenges. We looked across two categories: static, where each image grid is an individual target, and cross-tile challenges, where an object spans multiple tiles.
On static challenges, the agents performed respectably. Claude Sonnet 4.5 solved 47%. Gemini 2.5 Pro: 56%. GPT-5: 23%.
On cross-tile challenges: Claude scored 0%. Gemini: 2%. GPT-5: 1%.
In contrast, humans find cross-tile challenges easier than static ones. If you spot one tile that matches the target, your visual system follows the object into adjacent tiles automatically.
Agents find them nearly impossible. They evaluate each tile independently, produce perfectly rectangular selections, and fail on partial occlusion and boundary-spanning objects. They process the grid as nine separate classification problems. Humans process it as one scene.
The challenges hardest for humans -- ambiguous static grids where the target is small or unclear -- are easiest for agents. The challenges easiest for humans -- follow the object across tiles -- are hardest for agents. The difficulty curves are inverted. Not because agents are dumb, but because the two systems solve the problem with fundamentally different architectures.
Faking an output means producing the right answer. Faking a process means reverse-engineering the computational dynamics of a biological brain and reproducing them in real time. The first problem can be reduced to a machine learning classifier. The second is an unsolved scientific problem.
The standard objection is that any test can be defeated with sufficient incentive. But fraudsters weren't the ones who built the visual neural networks that defeated text CAPTCHAs -- researchers were. And they aren't solving quantum computing to undermine cryptography. The cost of spoofing an iris scan is an engineering problem. The cost of reproducing human cognition is a scientific one. These are not the same category of difficulty.

noticed that firefox gives 2x kHashes/s more than chrome (1000 vs 500)
I cannot get past the bot check (190kH/s), is it mining crypto on my laptop?
Yea it's pretty bad
Everybody says that bots put websites down, while marketing oriented folks start practicing AO (agent optimization) - to make their offerings even more available and penetrating.
Good luck banning yourself from the future.
What a great way to not get any traffic at all.
This sounds like something a bot would say.

The site is not protected by Anubis, it's blocked by it.
Closed.
Taking a 2024 report on bot loads on the Internet is like taking a 1950s Car & Driver article for modern vehicle stats.
That’s how fast the landscape is changing.
And remember: while the report might have been released in 2024, it takes time to conduct research and publish. A good chunk of its data was likely from 2023 and earlier.
Ok. So I get a page saying it’s verifying I’m not a bot with some kink of measurements per second and I don’t get through. Is that the point?
I don't get what it is or whether it's a satire or not.
If a webstie takes so long to verify me I'll bounce. That's it.

This is why I see (well managed) government digital IDs as sensible moves. Apart from DDOS attacks, if bots have to “prove” who they are on each request it seems like a win-win.
I may be missing something of course
AI companies and notably AI scrapers are a cancer that is destroying what's left of the WWW.
I was hit with a pretty substantial botnet "distributed scraping" attack yesterday.
- About 400,000 different IP addresses over about 3 hours
- Mostly residential IP addresses
- Valid and unique user agents and referrers
- Each IP address would make only a few requests with a long delay in between requests
It would hit the server hard until the server became slow to respond, then it would back off for about 30 seconds, then hit hard again. I was able to block most of the requests with a combination of user agent and referrer patterns, though some legit users may be blocked.
The attack was annoying, but, the even bigger problem is that the data on this website is under license - we have to pay for it, and it's not cheap. We are able to pay for it (barely) with advertising revenue and some subscriptions.
If everyone is getting this data from their "agent" and scrapers, that means no advertising revenue, and soon enough no more website to scrape, jobs lost, nowhere for scrapers to scrape for the data, nowhere for legit users to get the data for free, etc.
