I'm sorry to have to announce this, but I've added a captcha to the comment form.
Due to an overwhelming and unending amount of spam, I find myself forced to add a captcha in the hopes it will filter out the bots. I don't like captcha and I'm sure you don't like it either, but I am getting so much spam each month that it's either add a captcha or disable the comments entirely (or switch to a comment platform like Disqus or Livefyre, but I would rather close the comment section than deal with those folks).
According to akismet, this blog got 559,815 spam comments in December 2013. That is 10 times the amount of spam I had to deal with in December 2012, and there is no sign that the onslaught will abate any time soon. January promises to be just as busy; I've already had to deal with 341 thousand spam comments.
So at this point I cannot put it off any longer. Sorry.
