Earlier I was (still am) sick of spam mail. But, of late, I have been troubled by comment spam in my guestbook. I have been getting at least 5 spam comments everyday. What the spam comments do is that they sneak in a hyperlink to their site, which is usually some shady site hawking some shady wares/z. Google has already understood the magnitude of this problem and undertaken steps to handle it in their blogging system (blogspot, where you are reading this). But I am no google. For smaller guys like me, comment spam is becoming a major problem a la spam mail.
