Comment on WordPress SEO Nofollow by Jason Litka.
Nice post. I’m running Akismet on my site but lately I’ve been having 1 or 2 spam comments slip through per day and marking them as spam is messing up the RSS feed for my readers (it ends up showing everything in the feed as new) so I’ve been looking for something to augment it.
The “Bad Behavior” plugin you mentioned sounds like exactly what I want but the link is dead. Do you happen to have a copy you could post?
