Last month, Bernard blogged about context-specific spamming. Recently, I was a victim of this. Two of my blog entries have been placed with a comment about Indian marriages. The context is quite the same but the post appear to be more of an advertisement rather than that of something totally related to the post.
While closing the comments section to WordPress users only is a “solution”, it would limit the interactivity among the readers of the blog. I do hope WordPress provide a captcha posting for the free blogs as well.
