====MediaWiki, Wikipedia, and the Wikimedia Foundation====
[[wikipedia:MediaWiki|MediaWiki]] is of particular interest to LLM training due to the vast amount of factual, plain-text content wikis tend to hold. While [[wikipedia:Wikipedia|Wikipedia]] and the [[wikipedia:Wikimedia Foundation|Wikimedia Foundation]] host the most well-known wikis, numerous smaller wikis exist thanks to the work of many independent editors. The strength of wiki architecture is its ability for every edit to be audited by anyone, at any time - you can still view [https://en.wikipedia.org/w/index.php?oldid=1 the first edit to Wikipedia] from 2002. This makes wikis a hybrid of a static website and a dynamic web app, which becomes problematic when poorly-designed bots attempt to scrape them.<ref name="geraspora" />

<!-- COI alert: I, [[User:kirb]], am an admin for The Apple Wiki. Hopefully this is neutral enough?
-->The Apple Wiki, which documents internal details of Apple's hardware and software, holds more than 50,000 articles. On 2 August 2024, with a repeat occurrence on 5 January 2025, the service was disrupted by scraping efforts.<ref>https://theapplewiki.com/wiki/The_Apple_Wiki:Community_portal#Bot_traffic_abuse</ref> The wiki contains a considerable amount of information that is scraped by legitimate security research tools, making it difficult for the website to block non-legitimate requests. Efforts to block unethical scraping and protect the wiki have disrupted these legitimate tools. The large article count, combined with more than 280,000 total edits over the wiki's lifetime, create an untenable situation where it is simply not possible to scrape the website without causing significant service disruption.

On 1 April 2025, the Wikimedia Foundation indicated that its infrastructure has been under increasing pressure from content scraping bots since January 2024, with the particularly critical metric that "65% of our most expensive traffic comes from bots", despite estimating 35% of all traffic as coming from bots. The bots create traffic patterns that are significantly unlike human traffic patterns, effectively bypassing Wikimedia's caching infrastructure and placing significant load on the core servers. A blog post provides an example where bot traffic caused the [[wikipedia:Wikimedia Commons|Wikimedia Commons]] service to become unstable during a human traffic spike. The Foundation is considering introduction of a Responsible Use of Infrastructure policy to ensure the continued stability of their services.<ref>https://diff.wikimedia.org/2025/04/01/how-crawlers-impact-the-operations-of-the-wikimedia-projects/</ref>
