Too difficult to protect the site from botnets. googlebot, ybot, crawler bot is a botnet. 
RSS, feedback tool uses the same technique with a botnet. irc bot, bot scanner or a hacking 
tool that is also botnet. 
but has a different purpose. IRC bot, Bot scanner or a hacking tool is very disturbing, 
and its presence does not benefit us. from here the idea of making this Plugins. 
if the medium and high risk tool will implement the web status refused. 
and if a low risk web status can only be read to apply, can not upload or comment. 
Database on the plugin is taken from an existing tool. 
I hope this tool is useful for security and do not interfere with your SEO.

Don’t leave your barn door open! Lock down your admin login form and load up another site instead for unwanted guests.
On servers with limited memory, recursive calls to your WordPress admin login panel alone can lead to serious memory and load 
issues that can potentially crash your server. This plugin prevents access to 
the login screen without the correct access code appended to the url.
This plugin will kill the process of loading the admin panel prior to the loading of 
the template, and other such resource intensive processes that occur even when a user is not yet logged in.
How to Use 
1. Create your access code. 
2. Click the Activate Admin Lock checkbox. 
3. Optionally divert traffic to another url. 
4. Future admin login should use the following URL: 
http://www.yoursite.com/wp-admin/?a=CODE 
Where “CODE” is the access code you enter.
