* cmd/anubis: add a debug option for benchmarking hashrate Having the ability to benchmark different proof-of-work implementations is useful for extending Anubis. This adds a flag `--debug-benchmark-js` (and its associated environment variable `DEBUG_BENCHMARK_JS`) for serving a tool to do so. Internally, a there is a new policy action, "DEBUG_BENCHMARK", which serves the benchmarking tool instead of a challenge. The flag then replaces all bot rules with a special rule matching every request to that action. The benchmark page makes heavy use of inline styles, because currently all global styles are shared across all pages. This could be fixed, but I wanted to avoid major changes to the templates. * web/js: add signal for aborting an active proof-of-work algorithm Both proof-of-work algorithms now take an optional `AbortSignal`, which immediately terminates all workers and returns `false` if aborted before the challenge is complete. * web/js: add algorithm comparison to the benchmark page "Compare:" is added to the benchmark page for testing the relative performance between two algorithms. Since benchmark runs generally have high variance, it may take a while for the averages to converge on a stable difference. --------- Signed-off-by: Xe Iaso <me@xeiaso.net> Co-authored-by: Xe Iaso <me@xeiaso.net>

<summary>Why am I seeing this?</summary>
|
|
<p>You are seeing this because the administrator of this website has set up <a href="https://github.com/TecharoHQ/anubis">Anubis</a> to protect the server against the scourge of <a href="https://thelibre.news/foss-infrastructure-is-under-attack-by-ai-companies/">AI companies aggressively scraping websites</a>. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.</p>
|
|
<p>Anubis is a compromise. Anubis uses a <a href="https://anubis.techaro.lol/docs/design/why-proof-of-work">Proof-of-Work</a> scheme in the vein of <a href="https://en.wikipedia.org/wiki/Hashcash">Hashcash</a>, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.</p>
|
|
<p>Ultimately, this is a hack whose real purpose is to give a "good enough" placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.</p>
|
|
<p>Please note that Anubis requires the use of modern JavaScript features that plugins like <a href="https://jshelter.org/">JShelter</a> will disable. Please disable JShelter or other such plugins for this domain.</p>

Sadly, you must enable JavaScript to get past this challenge. This is required because AI companies have changed
|
|
the social contract around how website hosting works. A no-JS solution is a work-in-progress.
