{"slug": "802-11s-vlan-trunk-limitations-created", "title": "802.11s - VLAN Trunk Limitations - created", "summary": "The website hosting the page titled \"802.11s - VLAN Trunk Limitations\" is blocking visitors with an Anubis proof-of-work challenge, which the site's administrator deployed to stop aggressive scraping by AI companies. Anubis uses a Hashcash-style proof-of-work scheme that the site says is negligible at individual scale but adds up at mass scraper levels, and the administrator describes it as a placeholder until headless browsers can be identified via techniques such as font rendering. The challenge requires modern JavaScript features, so the site advises disabling plugins like JShelter for the domain.", "body_md": "# Testing to determine if you are a bot!\n\nLoading...\n\nYou are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.\n\nAnubis is a compromise. Anubis uses a Proof-of-Work scheme in the vein of Hashcash, 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.\n\nUltimately, this is a 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.\n\nPlease note that Anubis requires the use of modern JavaScript features that plugins like JShelter will disable. Please disable JShelter or other such plugins for this domain.", "url": "https://wpnews.pro/news/802-11s-vlan-trunk-limitations-created", "canonical_source": "https://openwrt.org/docs/guide-user/network/wifi/mesh/trunk-limitations?rev=1790191160&do=diff", "published_at": "2026-09-23 19:19:20+00:00", "updated_at": "2026-09-23 19:59:00.524905+00:00", "lang": "en", "topics": ["ai-crawlers"], "entities": ["Anubis", "Hashcash", "JShelter"], "alternates": {"html": "https://wpnews.pro/news/802-11s-vlan-trunk-limitations-created", "markdown": "https://wpnews.pro/news/802-11s-vlan-trunk-limitations-created.md", "text": "https://wpnews.pro/news/802-11s-vlan-trunk-limitations-created.txt", "jsonld": "https://wpnews.pro/news/802-11s-vlan-trunk-limitations-created.jsonld"}}
