When I woke up this morning, I found that there were some spam comments left by a guy. It’s clear that they were saved manually. There are always some guys keeping submitting spam comments in my blog, since they do it manually, my auto anti-spam plugins can’t prevent them. And I finally got tired of deleting manual spam comments, so I spent this sunday on this plugin, which is also my first plugin for wordpress. TODO Allow users to decide whether to ban spam comments directly or move them to the queue waiting to be audited. Allow users to specify the messages which are sent to commenters when their comments are banned. Validate URLs intelligently. i18n Save comments banning log to database.
