Block Spammers by IP address in WordPress

Sooner or later you’re going to have a bot relentlessly pinging your site and posting comments that link to undesirable sites.  Fortunately, stopping these tpyes from accessing the site is easy.
1) If it’s not already there, create a file named .htaccess in the root directory of your blog.

2) Add the following text:

order allow,deny
deny from 213.163.65.27
deny from 213.163.65.73
allow from all

3) As you receive new spam posts, add a new line to this file containing the offender’s ip address.

Hello world!

Welcome to WordPress. I can’t delete this, I’m always sentimental about my ‘hello worlds’.
