You may have noticed that you have comments waiting to be approved that look rather mysterious. I am not talking about the tons of viagra, cialis and porn spam every blog gets, I am talking about a trackback.
A trackback (or sometimes called pingback) is a method to allow to posts to reference each other. For example, if I write a post on my blog about Jane Smith’s article on blogging and include a link to her article in my post, a portion of my article and where it came from will be sent to Jane Smith’s comment section for her blogging post.
The problem with trackbacks is that spammers use them to. For instance, I received this trackback on another blog of mine:
However, when I clicked on the link, I was taken to a site that had a lot of pictures, mostly unsavory ones, and then the actual post hidden in an obscure place on the site. Do not automatically approve trackbacks before checking out the sites. There is not much you can do if they do link to you, but you don’t have to give them a link back!
