Playing whack-a-mole

No, this is not about raid healing. ;) I'm talking about gold seller comment spam on my blog. I'm playing a game of whack-a-mole with them, deleting all of their comments that try to direct people towards some gold selling website. This month has been particularly terrible, I'm getting several comment spams every day, and I wonder what I can do about it. I would hate to have to turn comment moderation on, or even turn commenting off, because I think the intelligent discussion of subjects by my readers is at least as valuable as my posts.

I don't understand why these gold sellers are so persistent. I have comment e-mail notification on, so I delete their comments several times a day, they are never up for more than a few hours. Even if they'd manage to get in just before the Google search engine scans my site, they wouldn't get any page rank from Google, because Blogger comments are automatically flagged as , denying them any search engine value.

The latest WoW gold seller is even leaving a sentence each on my posts that indicate he at least read what I was writing. Then he asks people to visit his blog, which contains only one entry which links to the gold selling site. I can't imagine that technique to bring him many visits, and I'm deleting his comments as well as the more direct ones.
