Loving this description on SEO Black Hat of accounts on Digg and the like (which has just announced “1 million users”). Describes multiple accounts created by one individual as “sock puppets”.
Heh. It works. Says SEO:
… it would be a hell of a lot more impressive if you told me you had 250,000 verified accounts – accounts that we knew tracked back to unique individuals. And no, verification emails to a freemail account don’t really count.
True – but careful. This *does* give fuel to ridiculous proposals like this from Germany.
