Developed by 10-year WP astronaut Jeff Starr, Blackhole Pro is a WordPress security plugin that automatically detects and traps bad bots in a virtual blackhole, where they are blocked from your site.

Bad bots are the worst. They do all sorts of nasty stuff and waste server resources. Blackhole Pro helps to stop bad bots and save server resources for legit visitors. In the words of Admiral Ackbar:

“It’s a Trap!”

Bye bye bad bots.. Blackhole Pro adds a hidden link to your pages. You add a rule to your robots.txt that instructs bots to stay away. Good bots will obey the rule, but bad bots will ignore it and follow the link.. right into the blackhole trap. Once trapped, bad bots are blocked and denied further access to your entire site. Benefits include: Stops leeches, scanners, and spammers Saves server resources for humans and good bots Improves traffic quality and overall site security
