Dear Heart... do we expect anything different? The bots, bot-handlers, and those scraping the web think they can sell urls they think are merchandising worthy to the clueless seeking the holy grail of MFA hoping to make a killing in a saturated market where data is rapidly becoming mundane?
My fun thought is that no matter how big hard drives become, or how fast the connections, anyone attempting to "index the web" is butt stupid since there is way too much slop out there which is not worth a plug nickle. The real giggle is they have to spend tons of funds to play their games. We, as webmasters, spend our dollars in business/connection. And we can kill their business profile in .htaccess or similar, and they can't hurt us that much.
