How do you handle requests associated with WordPress?
I'm seeing HEAD and GET requests from user agents like
WordPress/MU; http ://exampleblog.wordpress.com
WordPress.com mShots; http ://support.wordpress.com/contact/
(also mentioned here
...Or some standard browser user agent with a referer like http : //exampleblog.wordpress.com
I assume it's a link validation tool, but none of the above confirm exactly what it's looking for, and I'm annoyed that Wordpress doesn't care to provide a link to webmaster documentation.
Some of these Wordpress requests seem to originate from spam-friendly hosts like Planetlab... if a Wordpress hit is blocked with a 403 or 503, and assuming it's not a fake user agent, what happens on the blogger's end?
