This filter takes as string of text, analyzes it and returns either a 0 (not spam) or a 1 (spam). The spam filter is based on a scoring system which judges the following:

  • Word Count and Character Count.
  • How many URLs are in the post.
  • How many bad domain keywords, and path keywords in the post.
  • How many bad keywords are in the post.
  • How many constant characters are in a row.

Depending on the situation it could be given a positive score or a negative score. This combined with an overall score will give the post a percentage, based on that percentage and a threshold determined, it is then marked as spam or not spam.

Feel free to try it out at http://www.arthurwinters.net/beta
