I don't remember if it respects Crawl-Delay, but it respects forbidden paths, etc. I've never been DDOS'd by Baidu crawlers, but I did get DDOS'd by Yahoo a number of times. Turned out the solution was to disallow access to expensive-to-render pages. If you're using MediaWiki with prettified URLs, this works great: User-agent: * Allow: /mw/images/ Allow: /mw/skins/ Allow: /mw/title.png Disallow: /w/ Disallow: /mw/ Disallow: /wiki/Special: -- :wq
