One of our cs cart has had 100's of blog comments about Viagra get approved somehow since upgrading a few weeks ago. Any idea why and how to stop them?
The comments are on the blog home page rather than actual articles
Do you have Recaptcha configured to be used for your blog?
I'm also guessing that you allow posts to show without being approved. I.e. your blog is unmoderated. So a click-factory can post whatever they want to your blog.
