Suddenly, two days ago, I started getting credit card, hotel, and pharmacy affiliates spamming my comments feature on my Wordpress-based blog. When I started the blog I didn't allow comments because I didn't want to deal with this kind of stuff and every yahoo with a soapbox. Then I activated them because someone told me it would be better for search engine rankings and for surfers. So I allowed moderated comments. Now, I'm getting 10-20 spam comments a day.

I suppose it's nice to be famous, but I don't have a lot of blog experience with this. Is there anything I can do about this except decline the comments?

I thought I read something about a spam plugin.

Thanks
Michael
