I use hubpages or most of my linkwheels. The content I use is human readable, but clearly spun. Sentences make sense on their own, but taken together they make little sense and can be generally considered low quality. That said, they never get taken down. Anyway, what's been happening quite a lot lately is that when I upload my spun crap to a hub, I get fan-mail. On the last one I made, I got 5 fan mail messages saying "great hub, thanks!" and "Rockin' hub!". Why would people do this? My hubs are awful!
