Help, a lot of spam comment (I have TypePad antispam installed.)


I installed TypePad antispam and was very satisfied until a few days ago. I made researches before I install it, and found out that most people who use it were very satisfied. I was happy with it, but from a few days ago, I am starting to see a lot (about 70 so far and keep increasing) of spam comments.
It just copies other comments at random and post them again. What shall I do? Why do I have a lot of spam comments, while others are very satisfied?
Did I do anything wrong? I installed it in /mu-plugins and hard coded the serial code.
Please help me.

Thank you.
