I started this blog at the end of May. It has not been two months yet and already, I have over 600 comments.
I would feel a lot better if they were not almost all spam. I have received one genuine comment. I replied to it. The other comments are spam.
I have just installed Akismet. While I do not like CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) schemes, I also dislike having to wade through lots of spam.
If you have wondered why CAPTCHA is used so widely, now you know.
