Among the many things I did not know about blogging when I undertook to set up this blog is that there is a particular species of subhuman beast that attempts to avertise some product or service by posting "comments" on blogs like this one. The typical form is: "This is a very interesting post. Your readers may be interested to know that Phallix, a drug that give men huge erections that last for 3 months, is available for only $9.99 at your local pharmacy."
I have this blog set up to send me an e-mail when a reader posts a comment. Somehow these advertisers appear to know how to bypass that notification system. I do have control as blogger to pemanently eliminate any comments that I wish to, and whenever I discover one of these ads, I do so. (Those are the only comments that I have ever eliminated, as we have been very fortunate in not attracting comments that are full of obscenities, for instance.) However it may be some time between when the ad appears and when I come across it (or as happened in this latest case, when another faithful reader pointed it out to me). In the meantime please forgive this defacement of a blog that aims to provide noncommercial and valid information.
