Is there such a thing as Pingback spam? I started my first WordPress blog recently. I added a CAPTCHA because I was getting 7 spam posts per day after the blog reached only 12 posts! Ofcourse pingback messages from WordPress bypass the Captcha. When I follow the links in pingback messages, 2/3 of the time, there is no reference to my blog at all, and the subject on the blog is completely irrelevant. Is this another spam technique? Linking to do-follow blogs, just to get a pingback posted with a do-follow link?
