I was going to comment on Pete Blackshaws Post „Twitter Spam„, but unfortunately, the long and complex typekey registration process put me off. So I will comment here and trackback, why not. And I can even add my own screenshots.
In his post, Pete suspects twitter now having spam profiles. I second that, I have a Chinese Hotel,a kidney stones and a prostrate cancer follower. Seems like twitter is slowly becoming a playing field of professional spammers, too.
