I suppose the next "new" idea for a legitimate business model will be text scrapers that republish and monetise anything written on your website.
ehow already got there ..they added human re-spinners ( to disguise it ) and adsense ( from their pals at the plex ) to make boatloads of money off what isn't theirs ..
Pinterest invented "secret pinboards" [webmasterworld.com...] ( that is probably where they'll try putting ads first ) to hide the best stolen stuff from the rightful owners, who might be looking in the public facing stolen goods warehouse windows for their stuff..
Search engine's upload and search matching image search was getting too accurate for them to hide the stash in plain sight anymore..
For anyone reading ..this conversation thread with helleborine may also be useful.. [webmasterworld.com...]
