title: Filter Comment Spam? PHP
body: <p>I'm looking for articles on ways to filter spam. When I search around all I keep finding is Wordpress, ways to filter swear words etc which is not what I'm looking for. I'm looking for ways to write your own filter system and best practices.</p>
  
  <p>Any tutorial links from anyone who has done this before, would be appreciated.</p>
  
  <p>Only good article i can so far is <a href="http://snook.ca/archives/other/effective_blog_comment_spam_blocker" rel="noreferrer">http://snook.ca/archives/other/effective_blog_comment_spam_blocker</a></p>
