Yahoo! Once Again Caught Disobeying Robots.txt Rules

Hmmm.. Let’s see here. Google can do it. MSN/Live can do it. Even Ask can do it. So why oh why can’t Yahoo’s grubby Slurp crawler manage to adhere to robots.txt crawl directives? Just when I thought Yahoo! finally figured it out, I discover more Slurp tracks in my Blackhole trap for bad spiders:

I enjoy the control provided by the robots.txt protocol and look forward to the day when all of the major search engines get it right.

  1. This just shows that Google’s nearest competitor is just oh so far behind in the game.

    So true. I mean, how difficult is it for a computer to obey the operational rules it’s been given? I honestly can’t think of any excuse for Slurp’s recent deviancy into explicitly forbidden territory. Given that computers do not make “mistakes,” such illicit crawl behavior seems intentional. In either case, it’s not looking good for Yahoo.

Easily the most common exploit scan for WordPress is /{path}/wp-login.php.
