Initiating Probes Against Servers Via Other Servers

GRC's port probe scans only the requester's own IP, so RSnake sends the W3C validator to fetch it: the validator becomes the origin and reports the result back. Any GET-driven fetcher can be chained this way, so the scan logs as someone else's traffic and IP-based restriction does not hold.
