THe ultimate anti-blog spam!

I had a problem with blogspam in wordpress.
What I did was open up comments template in theme editor
and find the html markup for the comment field and javascript obsuficated it. like this

<script language="javascript">
document.write( unescape( '%3C%70%3E%3C%74%65%78%74%61%72%65%61%20%6E%61%6D%65%3D%22%63%6F%6D%6D%65%6E%74%22%20%69%64%3D%22%63%6F%6D%6D%65%6E%74%22%20%63%6F%6C%73%3D%22%36%30%22%20%72%6F%77%73%3D%22%31%30%22%20%74%61%62%69%6E%64%65%78%3D%22%34%22%3E%3C%2F%74%65%78%74%61%72%65%61%3E%3C%2F%70%3E'));
</script>

</script><?php echo $id; ?>" />

Code (markup):

No more blogspam for weeks now,

Online javascript obsuficator

Note: make sure only to obsufiscate HTML only. You cant obsuficate PHP tags.
What is does it when you visit the site your browser unescapes that string and it renders the obsuficated code. But too a spammer bot, it will not see the form. Meaning no spam.

If this gets rid of your spam , feel free to drop me a green
