We also have the new Nofollow plugin. That last one doesn’t stop spammers from posting to comments, but it does make it comments are not counted by the big search engines when they crawl pages; that in turn will limit spammers’ placement in search engines. The more people who install that plug-in, the better! It’s available for WordPress and probably other different blogging platforms, too.
With the first two in place, we hope to have unmoderated comments again…Yay! Don’t know about you, but we like the interaction in comments as much as we enjoy reading blog entries.
