Some thoughts on how useful Anubis really is. Combined with comments I read elsewhere about scrapers starting to solve the challenges, I'm afraid Anubis will be outdated soon and we need something else.

Unless you have a dirty heatsink, no amount of hammering would make the server overheat

    Are you explaining my own server to me? 🙄

    What CPU do you have made after 2004 that doesn't have automatic temperature control ?
    I don't think there is any, unless you somehow managed to disable it ?
    Even a raspberry pi without a heatsink won't overheat to shutdown

    You are right, it is actually worse, it usually just overloads the CPU so badly that it starts to throttle and then I can't even access the server via SSH anymore. But sometimes it also crashes the server so that it reboots, and yes that can happen on modern CPUs as well.

    You need to set you http serving process to a priority below the administrative processes (in the place where you are starting it, so assuming linux server that would be your init script or systemd service unit).

    Actual crash causing reboot ? Do you have faulty ram maybe ? That's really not ever supposed to happen from anything happenning in userland. That's not AI, your stuff might be straight up broken.

    Only thing that isn't broken that could reboot a server is a watchdog timer.

    You server shouldn't crash, reboot or become unreachable from the admin interface even at 100% load and it shouldn't overheat either, temperatures should never exceed 80C no matter what you do, it's supposed to be impossible with thermal management, which all processors have had for decades.

    Great that this is all theoretical 🤷 My server hardware might not be the newest but it is definitly not broken.

    And besides, what good is that you can still barely access the server through ssh, when the cpu is constantly maxed out and site visitors only get a timeout when trying to access the services?

    I don't even get what you are trying to argue here. That the AI scraper DDOS isn't so bad because in theory it shouldn't crash the server? Are you even reading what you are writing yourself? 🤡

    Why the hell don't you limit the CPU usage of that service?

    For any service that could hog resources so bad that they can block the entire system the normal thing to do is to limit their max resource usage. This is trivial to do using containers. I do it constantly for leaky software.

    Even if your server is a cell phone from 2015, if it's operating correctly and the cpu is maxed out, that means it's fully utilized and services hundreds of megabits of information.

    You've decided to let the entire world read from your server, that indiscriminatory policy is letting people you don't want getting your data, get your data and use your resources.

    You want to correct that by making everyone that comes in solve a puzzle, therefore in some way degrading their access, it's not surprising that they're going to complain. The other day I had to wait over 30 second at an anubis puzzle page, when I know that the AI scrappers have no problem getting through, something on my computer, probably some anti-crypto mining protection is getting triggered by it and now I can't no-script the web either because of that thing and it can't even stop scrappers anyway !

    So, anubis is going to be left behind, all the real users are, for years, going to be annoyed and have their entire internet degraded by it while the scrappers got that institutionally figured out in days.

    If it's freely available public data then the solution isn't restricting access trying to play a futile arms race with the scrapper and throwing the real users to the dogs, it's to have standardized incremental efficient database dumps so the scrappers stop assuming every website is interoperability-hostile and scrape them. Let facebook and xitter fight the scrappers, let anyone trying to leverage public (and especially user contributed data) fight the scrappers.

    Even if one would want to give them everything, they don't care. They just burn through their resources and recursively scrape every single link on your page. Providing standardized database dumps is absolutely not helping against your server being overloaded by scrapers of various companies with deep pockets.

    Like anubis, that's not going to last, the point isn't to hammer the web servers off the net, it's to get the precious data. The more standardized and streamlined that's going to be made and only if there's no preferential treatment to certain players (open ai / google facebook) then the dumb scraper will burn themselves out.

    One nice thing about anubis and nepenthes is that it's going to burn out those dumb scrapers faster and force them to become more sophisticated and stealth. That's should resolve the ddos problem on its own.

    For the truly public data sources, I think coordinated database dumps is the way to go, for hostile carrier, like reddit and facebook, it's going to be scrapper arms race warfare like Cory Doctorow predicted.

    Aha, an apologist for AI scraper DDOS, why didn't you say so directly instead of wasting my time?

    The ddos is caused by the gatekeeping, there was no such issue before the 2023 API wars, fork over the goods and nobody gets hurt, it's not complicated, you want to publish information to the public, don't scrunch it up behind diseased trackers and ad infested pages which burn you cpu cycles. Or just put it in a big tarball torrent, the web is turning into a cesspool, how long until our browsers don't even query websites at all but self-hosted crawler and search like searxng, at least then I won't be catching cooties from your javascript cryptomining bots embed into the pages !
