Password protect your WP login page! It's one of many, many improvements you can make to harden wordpress, against brute force attacks, DoS attacks, scannerz and scraperz and bots zombiez and vampirez etc.
on the command line:
> htpasswd -c /path/to/web/root/.wplogin your_name
then put this in your .htaccess:
AuthName "Restricted Access"
There are lots of wicked tutorials on the interweb explaining how to do that better than I have.
