I have been getting a lot of comment spam in the past couple of months. I tried to tackle the situation with various method (including, but not limited to) disabling anonymous comments and enabling CAPTCHA. However, as nothing seems to have worked reliably, I am left with nothing but enforce comment moderation. Keep in mind that this blog isn't a democracy, but a dictatorship and I am the dictator. So, don't ever think about complaining of the moderation, whatsoever! This is my first and last decision. Well, at least for now. ;)
Edit: Almost all the spam comments have been cleared!
