FindFilesBot

Verifiable

The crawler behind the FindFiles.net file search engine. It checks that publicly accessible files users search for are still available, using multiplexed HTTP/2 HEAD requests with a minimum ten-second interval per server, and may download images, videos and executables for classification and safety checks. Purpose-specific user agents are published for its link checking, favicon fetching, virus scanning and image classification agents, which all share one crawler host and address.
