Comment Spam

The thing I am doing today is going to all my blogs and resetting them to block comment spam. It is so disappointing to open a comment, thinking someone has finally read the blog, when it says something like 'nice blog, now come over here and buy penny stocks'. I'm glad I found out how to do it today by clicking on 'settings', then on 'comments' and clicking the box to make them type in a passcode to leave a comment.
