This means they've found a way to bypass the Facebook Captcha (the image of letters which are required for a new account, which are supposed to ensure that a human is involved). The result is that they have created automated attacks coming from Facebook.

Thompson found a series of identical Facebook profiles which contained the same picture of a woman. Click on the picture (and probably on other things in the profile) and you see a typical fake anti-malware, or scareware, attack. As Thompson says, Facebook will kill them off as they find them, but they can't be easy to find and now there will be a lot of them.
