Kindred minds :)
Given that they will keep "spark" in the name in some form for a while ..it may be possible to spot the presence and even the name of the toolbar / clipper / whatever on the browser ( should work for other companies "scrape" tools that are as browser add ons too ) and either load /write scripts ( possibly on the fly ), to disable them ..or redirect the visitor who has them on their browser to "something else"..
"include" on every page..and like you say ..site wide that particular vector is stymied..
Something to while away some time..
A thought just struck me ..way to freak out the users of these scraper tools ..use one of the many "shake the page" ( including the text ) script commands, if they are detected using any of these things..:)
