Description
This will allow you to automatically scan new posts from new members for common spam keywords. If any are found, the post/thread will be sent to the moderation queue to prevent their spam from having any affect. If your filter is very strict, and a regular user happens to trigger it, no harm is done because your moderators can just approve the post.
Options
Maximum Posts - this will only scan posts posted by users who have this many (or less) posts. Usually spammers only post 1-5 times!
Keywords - a list of keywords (or any strings) to be searched. Remember it doesn't match a whole word, so a keyword of "[url" will block the user from posting any links. This is NOT case sensitive!
