It depends on your definition of "ethical"
Adam Gaffin at Universal Hub draws our attention to a new “service” in which you pay for “relevant” comments to be left on “high-page-rank blogs”, which helps your site “rank better in the SERPs.” (SERP = Search Engine Result Page.)
The part I find most amusing is their attempts at self-justification:
YES, Buying Blog Comments is 100% ethical and NOT spam!
…and yet they’re spending the rest of the page explaining how their technique leaves comments which won’t be deleted by the site moderator. Now why would a site moderator ever want to delete 100% ethical, not-spam comments?
(If there’s any confusion in your mind, buying blog comments is 100% unethical and is spam.)
No extra points for counting the spelling and grammatical errors. Note that I have used rel="nofollow" on the link to the sleazy ones.
