Just a quick post here, since there’s not too much to say about this one.

I received the comment below on one of the blogs I administer:

Hi, I left you a DOFOLLOW backlink on my website. This isnt a spam message, i actually did leave you a backlink on my site. If you check the top of the page you will see “Sites we like” and there will be a link to this site. Would you be kind enough to leave me a backlink? If so my website is http://[SCREW YOU, SPAMMER].com please use the anchor text “[I AM A STUPID SPAMMER]” for the link and add it to a post or as a widget. Then please send me a email at backlink@[NOT A CHANCE].com – If you want me to change your links anchor text let me know. Thanks

Since I’m the curious type, I decided to visit the site. Imagine my surprise when the backlink is actually there!

Being that the top of the home page is an extremely unlikely place for a backlink, I entered the URL directly. As expected, the link disappeared.

So, it’s checking the referrer, and displaying the link to one of the sites spammed when the correct referrer is found. Not a new trick, but pretty clever.
