Add your own virtual Blackhole trap for bad bots. The Blackhole plugin includes a hidden link to your pages. You then add a line to your robots.txt file that forbids bots from following the hidden link. Bots that ignore or disobey your robots rules will crawl the link and fall into the trap. Once trapped, bad bots are denied further access to your WordPress-powered website.
I call it the "one-strike" rule: bots have one chance to obey your site's robots.txt rule. Failure to comply results in immediate banishment. The best part is that the Blackhole only affects bad bots: human users never see the hidden link, and good bots obey the robots rules in the first place. Win-win! :)

Whitelist
By default, this plugin does NOT block any of the major search engines:
- AOL.com
- Baidu
- Bingbot/MSN
- DuckDuckGo
- Googlebot
- Teoma
- Yahoo!
- Yandex
These search engines (and all of their myriad variations) are whitelisted. They always are allowed full access to your site, even if they disobey your robots.txt rules. This list can be customized in the plugin settings.
