Hey... quick question, why are anime catgirls blocking my access to the Linux kernel? 😸 lock.cmpxchg8b.com/anubis.ht…

because companies like your employer's are destroying the commons by abusing the limited budgets of individuals and smaller organizations who put content online and this is literally what it has come to

That sucks, but my employer has datacenters all over the world, 2^16 SHA2 operations is literally too small to even measure? For people on limited devices however... 😬

It's not perfect, but it's a fast, dirty way to block AI scrapers. zdnet.com/article/fed-up-wit…

Fed up with AI scraping your content? This open-source bot blocker can help - here's how

Meet Anubis, the self-hosted firewall that's stopping AI bots in their tracks.

I understand the intention, the article is explaining why I think the solution has the problem inverted?

I am completely new to this topic, but what you have said seems correct in theory. Do you know if any website published real data comparing traffic before and after implementing anubis?

You must submit proof that you own a pair of cat ears to prove that you’re a kernel developer

It's not a catgirl. It's a doggirl. en.wikipedia.org/wiki/Anubis

also, fun fact, you can get rid of the anime catgirl by just using non-browser user agents. would be a real shame if someone built a browser extension that does that automatically when detecting anubis 🤭 addons.mozilla.org/en-US/fir…

NoPoW – Get this Extension for 🦊 Firefox (en-US)

Download NoPoW for Firefox. Removes annoying Proof-of-Work/PoW captchas by changing the user-agent.

Protip: Change your useragent to curl Anubis is literally the worst thing that's happened to the interent in ages

I think a few big/notable open-source projects use Anubis because ... it seems to work? I think the interesting question is why - it's just enough of a metaphorical "locked door" such that AI crawlers would look *too sleazy* if they just "kicked it down"? For now?

Huawei bots can already bypass this

Cool blog post, just finished reading thru it. I liked the links to relevant info like the register and wiki pages.

Perhaps Anubis works because the most aggressive bots are not browsers, they just pretend to be one, and do not execute JS. Browser-based bots presumably pass Anubis, but they don't hammer servers as much, so it's a win (for now)

About the article: could you redo your calculations for the cost(s), by *assuming* the AI bots are (1) independent, (2) don't have a cookie file, and tries to access ~300k pages + ~3*300k images (a site I sysadmin for)

I’d argue it’s “because we can’t have nice things” and if you allow bots to scrape your site they will take down your infrastructure and hosting costs will go up. But still weird that it’s an anime girl, you couldn’t find a different mirror?

You seam to have found yourself in a hairy situation. Why is it as if it was written on the wall in 1999? The cats changed slightly, but: cats!

why does half of software online have anime girls in there 😭 i overall dont like any sort of companions in apps/websites because they look cringe but this? this is just my personal preference though of not wanting to see this

That's Anubis, and it's a jackal, not a cat.

My understanding was that the goal is to make it expensive to switch your browser's "identity" around to bypass regular rate limiting. You either stick to the same and get rate limited, or get slowed by the hashes, targeted website gets some breathing room either way.
