Welcome to the Q&A Forum

What's the best way to stop Wordpress spam? We don't let comments go live without moderation, so the spammers don't succeed, however it wastes time going through the comments. A captcha code could work but a lot of software can crack it. Are there any good captcha solutions or could something else work better/in conjunction? Also, is there anywhere to report spam IP addresses? Not sure much happens when you mark a comment as spam in Wordpress.
