Have you read this comment?

@ebitularmbert, I had to flag the spammer after he ignored your advice. He left spam on my blog a week ago so I asked him what he meant, and I got no reply. I have taken his reputation back down to 25 from 40. Can take him lower if he continues.

Imagine at reputation 25, where you will be at, if the same should happen! You might want to think thrice, before you spam comment again! @prabu
