Spam is a big annoyance when you have a web site. You get all of these comments, mainly from one particular IP address, which you have to process and delete. In an effort to prevent spam from cluttering up my site. I have added reCaptcha to comments. If you are a human and you want to comment on an article, reCaptcha will ask you to type in the two (2) words it chooses at random and displays, just below the comment form. In order for your comment to be passed through to me, you will need to enter those 2 words, no automatics system need apply.
Hopefully this will stem the tide and eliminate most of the spam comments, wish me luck.
