These things work by - if they don't know the answer, like the weather, or math, or via maps - they query a known good source such as wikipedia or whatever. (No idea how to edit a wikipedia page) - couldn't you do the usual email trick of loading an image via a server side script (say, a php script that serves an image) that tracks the image being loaded - even though it's not presenting the image, it might still be requesting it, no ? (I might be completely wrong)
