One of my favorite security measures here at Perishable Press is the site’s virtual Blackhole trap for bad bots. The concept is simple: include a hidden link to a robots.txt-forbidden directory somewhere on your pages.
Bots that ignore or disobey your robots rules will crawl the link and fall into the trap, which then performs a WHOIS Lookup and records the event in the blackhole data file. Once added to the blacklist data file, bad bots immediately are denied access to your site. I call it the “one-strike” rule: bots have one chance to follow the robots.txt protocol, check the site’s robots.txt file, and obey its directives.
Failure to comply results in immediate banishment. In five easy steps, you can set up your own Blackhole to trap bad bots and protect your site from evil scripts, bandwidth thieves, content scrapers, spammers, and other malicious behavior. The Blackhole is built with PHP, and uses a bit of .htaccess to protect the blackhole directory. Installation Overview. Good PHP Tutorials - Beginner To Advanced PHP Programming Tutorials.
