Are you seeing more spam trackbacks listed in WordPress comments?
A trackback helps to notify another author that something related was written to what the they wrote, even if you don’t have an explicit link to his article. This improves the chances of the other author sitting up and noticing that you gave him credit for something, or that you improved upon something he wrote, or something similar. With pingback and trackback, blogs are interconnected. Think of them as the equivalents of acknowledgements and references at the end of an academic paper, or a chapter in a textbook.
That’s the way they are supposed to work. But spammers are also using them to bring unwanted comments into your site.
A pingback is an actual link to another blog contained within a post. You can read about them in this post.
