I monitor traffic on my server and I noticed a recent upswing in the hits on this blog. Normally, I would be impressed, but I know I have said nothing profound in a significant amount of time (or possibly ever) so I began to search for another explanation.
It turns our a new group of spammers seem to have located this blog and are attempting to add “comment spam”. The filter I use seems to be very effective and to my knowledge no inappropriate comments are actually being served. However, I may miss appropriate attempts to add a comment. I have to approve comments before they appear on the site and the experience is something like going through your mail without a spam filter. I glance through about 500 or so comments every day now and 99.9%+ are spam. My experience has been that this problem will go away when those responsible are unable to achieve the desired results.
My apologies if I have missed your comment.
